Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES	BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES The accompanying Condensed Consolidated Financial Statements of Qorvo, Inc. and Subsidiaries (together, the "Company" or "Qorvo") have been prepared in conformity with accounting principles generally accepted in the United States ("U.S. GAAP"). The preparation of these financial statements requires management to make estimates and assumptions, which could differ materially from actual results. In addition, certain information or footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed, or omitted, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). In the opinion of management, the financial statements include all adjustments (which are of a normal and recurring nature) necessary for the fair presentation of the results of the interim periods presented. These Condensed Consolidated Financial Statements should be read in conjunction with the Company's audited consolidated financial statements and notes thereto included in Qorvo’s Annual Report on Form 10-K for the fiscal year ended March 31, 2018. The Condensed Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The Company uses a 52- or 53-week fiscal year ending on the Saturday closest to March 31 of each year. The first fiscal quarter of each year ends on the Saturday closest to June 30, the second fiscal quarter of each year ends on the Saturday closest to September 30 and the third fiscal quarter of each year ends on the Saturday closest to December 31. Fiscal years 2019 and 2018 are 52-week years.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
RECENT ACCOUNTING PRONOUNCEMENTS	RECENT ACCOUNTING PRONOUNCEMENTS The Company assesses recently issued accounting standards by the Financial Accounting Standards Board ("FASB") to determine the expected impacts on the Company's financial statements. The summary below describes impacts from newly issued standards as well as material updates to our previous assessments, if any, from Qorvo’s Annual Report on Form 10-K for the fiscal year ended March 31, 2018. In January 2017, the FASB issued Accounting Standards Update ("ASU") 2017-01, "Business Combinations (Topic 805): Clarifying the Definition of a Business." The new guidance clarifies the definition of a business and provides further guidance for evaluating whether a transaction will be accounted for as an acquisition of an asset or a business. The new standard became effective for the Company in the first quarter of fiscal 2019. There was no impact to the Company's Condensed Consolidated Financial Statements. In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the FASB’s Emerging Issues Task Force)." The new guidance addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The new standard became effective for the Company in the first quarter of fiscal 2019. The Company's historical policies were consistent with the new standard, and therefore, there was no impact to the Company's Condensed Consolidated Financial Statements. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." The new guidance requires lessees to recognize a right-of-use asset and a lease liability for all leases with a term longer than 12 months, including those previously described as operating leases. Consistent with current U.S. GAAP, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee will primarily depend on its classification as a finance or operating lease. The new guidance will become effective for the Company in the first quarter of fiscal 2020. The Company expects the valuation of the right-of-use assets and lease liabilities, for leases previously described as operating leases, to be the present value of its forecasted future lease commitments, as determined by the standard. The Company is continuing to assess the overall impacts of the new standard, including the discount rate to be applied in these valuations. In January 2016, the FASB issued ASU 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." The new guidance affects the accounting for equity investments, financial liabilities measured under the fair value option and presentation and disclosure requirements for financial instruments. In addition, the FASB clarified guidance related to the assessment of valuation allowances when recognizing deferred tax assets related to unrealized losses on available-for-sale debt securities. The new standard was adopted by the Company in the first quarter of fiscal 2019. There was no impact to the Company's Condensed Consolidated Financial Statements. In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)," with several amendments subsequently issued. The new guidance provides an updated framework for revenue recognition, resulting in a single revenue model to be applied by reporting companies under U.S. GAAP. Under the new model, recognition of revenue occurs when a customer obtains control of promised goods or services in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company adopted the standard in the first quarter of fiscal 2019 using the modified retrospective approach, under which the cumulative effect of adoption is recognized at the date of initial application. This standard did not have a material impact on the Company's Condensed Consolidated Financial Statements. The Company has implemented changes to its accounting policies, internal controls and disclosures to support the new standard; however, these changes were not material. See Note 8 for further disclosures resulting from the adoption of this new standard.

Equity Investment Without a Readily Determinable Fair Value

As of September 29, 2018, the Company has invested $60.0 million to acquire preferred shares of a private limited company. This investment is classified in "Long-term investments" in the Condensed Consolidated Balance Sheets. This investment was determined to be an equity investment without a readily determinable fair value and is accounted for using the measurement alternative in accordance with ASU 2016-01. As of September 29, 2018, there was no impairment or observable price change for this investment.

Fair Value of Financial Instruments

Marketable securities are measured at fair value and recorded in "Cash and cash equivalents," "Short-term investments" and "Long-term investments" in the Condensed Consolidated Balance Sheets, and the related unrealized gains and losses are included in "Accumulated other comprehensive loss," a component of stockholders’ equity, net of tax.

Recurring Fair Value Measurements

The fair value of the financial assets measured at fair value on a recurring basis was determined using the following levels of inputs as of September 29, 2018 and March 31, 2018 (in thousands):

(1) ARS are debt instruments with interest rates that reset through periodic short-term auctions. The Company’s Level 2 ARS are valued based on quoted prices for identical or similar instruments in markets that are not active.

(2) The Company's non-qualified deferred compensation plan provides eligible employees and members of the Board of Directors with the opportunity to defer a specified percentage of their cash compensation. The Company includes the assets deferred by the participants in the “Other current assets” and “Other non-current assets” line items of its Condensed Consolidated Balance Sheets and the Company's obligation to deliver the deferred compensation in the "Other current liabilities" and “Other long-term liabilities” line items of its Condensed Consolidated Balance Sheets.

As of September 29, 2018 and March 31, 2018, the Company did not have any Level 3 assets or liabilities.

Other Fair Value Disclosures

The carrying values of cash and cash equivalents, accounts receivable, accounts payable and other accrued liabilities approximate fair values because of the relatively short-term maturities of these instruments. See Note 6 for further disclosures related to the fair value of the Company's long-term debt.

The 2023 Notes were, and the 2025 Notes are, senior unsecured obligations of the Company and guaranteed, jointly and severally, by the Company and certain of its U.S. subsidiaries (the "Guarantors"). The 2023 Notes and the 2025 Notes were issued pursuant to an indenture dated as of November 19, 2015 (the "2015 Indenture"), by and among the Company, the Guarantors and MUFG Union Bank, N.A., as trustee. The 2015 Indenture contains customary events of default, including payment default, failure to provide certain notices and certain provisions related to bankruptcy events.

In March 2018, the Company repurchased $5.5 million and $1.5 million of the 2023 Notes and the 2025 Notes, respectively, at prices equal to 107.50% of the principal amount of the 2023 Notes purchased, plus accrued and unpaid interest, and 109.50% of the principal amount of the 2025 Notes purchased, plus accrued and unpaid interest.

On August 28, 2018, following an increase of the tender cap to $140.0 million, the Company completed the purchase of $136.4 million aggregate principal amount of the 2025 Notes at a price equal to 110.00% of the principal amount of the 2025 Notes purchased, plus accrued and unpaid interest.

During the three and six months ended September 29, 2018, the Company recognized a loss on debt extinguishment of $48.8 million and $82.2 million, respectively, as "Other expense" in the Company’s Condensed Consolidated Statements of Income.

At any time prior to December 1, 2020, the Company may redeem all or part of the 2025 Notes, at a redemption price equal to their principal amount, plus a “make whole” premium as of the redemption date, and accrued and unpaid interest. In addition, at any time prior to December 1, 2018, the Company may redeem up to 35% of the original aggregate principal amount of the 2025 Notes with the proceeds of one or more equity offerings, at a redemption price equal to 107.00% of the principal amount of the 2025 Notes redeemed, plus accrued and unpaid interest. Furthermore, at any time on or after December 1, 2020, the Company may redeem the 2025 Notes, in whole or in part, at the redemption prices specified in the 2015 Indenture, plus accrued and unpaid interest.

With respect to the 2023 Notes, interest was payable on June 1 and December 1 of each year at a rate of 6.75% per annum, and with respect to the 2025 Notes, interest is payable on June 1 and December 1 of each year at a rate of 7.00% per annum.

On August 28, 2018, the Company completed an offering of an additional $130.0 million aggregate principal amount of such notes (the "Additional 2026 Notes", together with the "Initial 2026 Notes", the "2026 Notes"). The 2026 Notes pay interest semi-annually on January 15 and July 15 at a rate of 5.50% per annum. The 2026 Notes will mature on July 15, 2026, unless earlier redeemed in accordance with their terms. The 2026 Notes are senior unsecured obligations of the Company and are initially guaranteed, jointly and severally, by its Guarantors.

The Initial 2026 Notes were issued pursuant to an indenture, dated as of July 16, 2018 by and among the Company, the Guarantors and MUFG Union Bank, N.A., as trustee, and the Additional 2026 Notes were issued pursuant to a supplemental indenture, dated as of August 28, 2018 (together, the "2018 Indenture"). The 2018 Indenture contains customary events of default, including payment default, exchange default, failure to provide certain notices thereunder and certain provisions related to bankruptcy events and also contains customary negative covenants.

The 2026 Notes were sold in a private offering to certain institutions that then resold the 2026 Notes in the United States to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the "Securities Act"), and to certain non-U.S. persons in accordance with Regulation S under the Securities Act. The Company used a portion of the net proceeds of the 2026 Notes to fund the tender offers for the 2025 Notes and to pay related fees and expenses of the offering and will use the remaining net proceeds for general corporate purposes.

At any time prior to July 15, 2021, the Company may redeem all or part of the 2026 Notes, at a redemption price equal to their principal amount, plus a “make-whole” premium as of the redemption date, and accrued and unpaid interest. In addition, at any time prior to July 15, 2021, the Company may redeem up to 35% of the original aggregate principal amount of the 2026 Notes with the proceeds of one or more equity offerings, at a redemption price equal to 105.50% of the principal amount of the 2026 Notes redeemed, plus accrued and unpaid interest. Furthermore, at any time on or after July 15, 2021, the Company may redeem the 2026 Notes, in whole or in part, at the redemption prices specified in the 2018 Indenture, plus accrued and unpaid interest.

The 2026 Notes have not been registered under the Securities Act, or any state securities laws, and, unless so registered, may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and applicable state securities laws.

In connection with the offering of the 2026 Notes, the Company entered into a registration rights agreement, dated as of July 16, 2018, by and among the Company and the Guarantors, on the one hand, and Merrill Lynch, Pierce, Fenner & Smith Incorporated, as representative of the initial purchasers of the Initial 2026 Notes, on the other hand, and a substantially similar agreement, dated as of August 28, 2018 with respect to the Additional 2026 Notes (together, the "Registration Rights Agreements").

Under the Registration Rights Agreements, the Company and the Guarantors have agreed to use their commercially reasonable efforts to (i) file with the SEC a registration statement (the "Exchange Offer Registration Statement") relating to the registered exchange offer (the "Exchange Offer") to exchange the 2026 Notes for a new series of the Company’s exchange notes having terms substantially identical in all material respects to, and in the same aggregate principal amount as, the 2026 Notes; (ii) cause the Exchange Offer Registration Statement to be declared effective by the SEC; and (iii) cause the Exchange Offer to be consummated no later than the 360th day after July 16, 2018 (in the case of the Initial 2026 Notes) or August 28, 2018 (in the case of the Additional 2026 Notes) (or if such 360th day is not a business day, the next succeeding business day). The Company and the Guarantors have also agreed to use their commercially reasonable efforts to cause the Exchange Offer Registration Statement to be effective continuously and keep the Exchange Offer open for a period of not less than the minimum period required under applicable federal and state securities laws to consummate the Exchange Offer.

Under certain circumstances, the Company and the Guarantors have agreed to use their commercially reasonable efforts to (i) file a shelf registration statement relating to the resale of the 2026 Notes as promptly as practicable, and (ii) cause the shelf registration statement to be declared effective by the SEC as promptly as practicable. The Company and the Guarantors have also agreed to use their commercially reasonable efforts to keep the shelf registration statement continuously effective until one year after its effective date (or such shorter period that will terminate when all the 2026 Notes covered thereby have been sold pursuant thereto).

If the Company fails to meet any of these targets, the annual interest rate on the 2026 Notes will increase by 0.25% during the 90-day period following the default, and will increase by an additional 0.25% for each subsequent 90-day period during which the default continues, up to a maximum additional interest rate of 1.00% per year. If the Company cures the default, the interest rate on the 2026 Notes will revert to the original rate.

Credit Agreement

On December 5, 2017, the Company and the Guarantors entered into a five-year unsecured senior credit facility pursuant to a credit agreement with Bank of America, N.A., as administrative agent (in such capacity, the “Administrative Agent”), swing line lender and L/C issuer, and a syndicate of lenders (the "Credit Agreement"). On June 5, 2018, the Company and the Guarantors entered into the First Amendment (the "Amendment") to the Credit Agreement. The Credit Agreement includes a senior delayed draw term loan of up to $400.0 million (the "Term Loan") and a $300.0 million senior revolving line of credit (the "Revolving Facility", together with the Term Loan, the "Credit Facility"). On the closing date, $100.0 million of the Term Loan was funded (and subsequently repaid in March 2018), with the remainder available, at the discretion of the Company, in up to two draws. The Amendment, among other things, extended the delayed draw availability period from June 5, 2018 to January 3, 2019. The Revolving Facility includes a $25.0 million sublimit for the issuance of standby letters of credit and a $10.0 million sublimit for swing line loans. The Company may request that the Credit Facility be increased by up to $300.0 million, subject to securing additional funding commitments from the existing or new lenders. The Credit Facility is available to finance working capital, capital expenditures and other corporate purposes. Outstanding amounts are due in full on the maturity date of December 5, 2022 (with amounts borrowed under the swingline option due in full no later than ten business days after such loan is made), subject to scheduled amortization of the Term Loan principal as set forth in the Credit Agreement prior to the maturity date. During the six months ended September 29, 2018, there were no borrowings under the Revolving Facility and the Company had no outstanding amounts under the Credit Facility as of September 29, 2018.

The Credit Agreement contains various conditions, covenants and representations with which the Company must be in compliance in order to borrow funds and to avoid an event of default. As of September 29, 2018, the Company was in compliance with these covenants.

Fair Value of Long-Term Debt

The fair value of the 2025 Notes as of September 29, 2018 and March 31, 2018 was $120.0 million and $596.5 million, respectively (compared to a carrying value of $112.1 million and $548.5 million, respectively). The fair value of the 2026 Notes as of September 29, 2018 was $641.0 million (compared to a carrying value of $630.0 million). The Company considers its long-term debt to be Level 2 in the fair value hierarchy. Fair values are generally estimated based on quoted market prices for identical or similar instruments. The 2025 Notes and 2026 Notes trade over the counter and their fair values were estimated based upon the value of their last trade at the end of the period.

Interest Expense

During the three and six months ended September 29, 2018, the Company recognized $10.9 million and $28.0 million, respectively, of interest expense related to the 2023 Notes, 2025 Notes and the 2026 Notes, which was partially offset by $1.8 million and $5.3 million, respectively, of interest capitalized to property and equipment. During the three and six months ended September 30, 2017, the Company recognized $17.3 million and $34.6 million, respectively, of interest expense related to the 2023 Notes and the 2025 Notes, which was partially offset by $3.2 million and $8.8 million, respectively, of interest capitalized to property and equipment.

Equity [Abstract]
STOCK REPURCHASES	STOCK REPURCHASES On May 23, 2018, the Company announced that its Board of Directors authorized a share repurchase program to repurchase up to $1.0 billion of the Company's outstanding stock, which included approximately $126.3 million authorized under a prior share repurchase program which was terminated concurrent with the new authorization. Under this program, share repurchases are made in accordance with applicable securities laws on the open market or in privately negotiated transactions. The extent to which the Company repurchases its shares, the number of shares and the timing of any repurchases depends on general market conditions, regulatory requirements, alternative investment opportunities and other considerations. The program does not require the Company to repurchase a minimum number of shares, does not have a fixed term, and may be modified, suspended or terminated at any time without prior notice. During the three months ended September 29, 2018, the Company repurchased approximately 1.1 million shares of its common stock for approximately $86.7 million under the current share repurchase program. During the six months ended September 29, 2018, the Company repurchased approximately 2.3 million shares of its common stock for approximately $186.7 million (which included 0.4 million shares of its common stock for approximately $35.9 million under a prior share repurchase program). As of September 29, 2018, $849.2 million remains available for repurchases under the current share repurchase program. During the three and six months ended September 30, 2017, the Company repurchased approximately 0.8 million shares and 1.2 million shares of its common stock for approximately $57.0 million and $88.9 million, respectively, under a prior share repurchase program.

Revenue from Contract with Customer [Abstract]

REVENUE

Change in Accounting Policy

The Company adopted ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)," in the first quarter of fiscal 2019 for open contracts using the modified retrospective approach through a cumulative adjustment to "Accumulated deficit" in the Condensed Consolidated Balance Sheet for the fiscal year beginning April 1, 2018. The impact from the cumulative-effect adjustment was immaterial (less than 1% of revenue in the quarter of adoption), related to over-time revenue recognition for customer-controlled inventory and point in time revenue recognition for intellectual property with a right to use. As the adoption of ASU 2014-09 did not have a material impact, comparative financial information for prior periods has not been restated and continues to be presented under the accounting standards in effect for the respective periods.

Revenue Recognition Policy

The Company generates revenue primarily from the sale of semiconductor products, either directly to a customer or to a distributor, or at completion of a consignment process. Revenue is recognized when control of the promised goods or services is transferred to the Company's customers, in an amount that reflects the consideration it expects to be entitled in exchange for those goods or services. A majority of the Company's revenue is recognized at a point in time, either on shipment or delivery of the product, depending on individual customer terms and conditions. Revenue from sales to the Company’s distributors is recognized upon shipment of the product to the distributors (sell-in). Revenue is recognized from the Company’s consignment programs at a point in time when the products are pulled from consignment inventory by the customer. Revenue recognized for product and services over-time is immaterial (less than 2% of overall revenue). The Company applies a five-step approach as defined in the new standard in determining the amount and timing of revenue to be recognized: (1) identifying the contract with a customer; (2) identifying the performance obligations in the contract; (3) determining the transaction price; (4) allocating the transaction price to the performance obligations in the contract; and (5) recognizing revenue when the corresponding performance obligation is satisfied.

Sales agreements are in place with certain customers and contain terms and conditions with respect to payment, delivery, warranty and supply, but typically do not require minimum purchase commitments. In the absence of a sales agreement, the Company’s standard terms and conditions apply. The Company considers a customer's purchase order, which is governed by a sales agreement or the Company’s standard terms and conditions, to be the contract with the customer.

The Company’s pricing terms are negotiated independently, on a stand-alone basis. In determining the transaction price, the Company evaluates whether the price is subject to refund or adjustment to determine the net consideration to which the Company expects to be entitled. Variable consideration in the form of rebate programs is offered to certain customers, including distributors. These rebates represent less than 5% of net revenue. The majority of these accruals are classified as a contra accounts receivable. The Company determines variable consideration by estimating the most likely amount of consideration it expects to receive from the customer. The Company's terms and conditions do not give its customers a right of return associated with the original sale of its products. However, the Company may authorize sales returns under certain circumstances, which include courtesy returns and like-kind exchanges. Sales returns are classified as a refund liability. The Company reduces revenue and records reserves for product returns and allowances, rebate programs and scrap allowance based on historical experience or specific identification depending on the contractual terms of the arrangement.

The Company’s accounts receivable balance is from contracts with customers and represents the Company’s unconditional right to receive consideration from its customers. Payments are due within one year of completion of the performance obligation and subsequent invoicing and, therefore, do not include significant financing components. To date, there have been no material impairment losses on accounts receivable. Contract assets and contract liabilities recorded on the Condensed Consolidated Balance Sheets were immaterial in the periods presented.

The Company invoices customers upon shipment and recognizes revenues in accordance with delivery terms. As of September 29, 2018, the Company had $41.6 million in remaining unsatisfied performance obligations with an original duration greater than one year, of which the majority is expected to be recognized as income over the next twelve months.

The Company includes shipping charges billed to customers in "Revenue" and includes the related shipping costs in "Cost of goods sold" in the Condensed Consolidated Statements of Income. Taxes assessed by government authorities on revenue-producing transactions, including tariffs, value-added and excise taxes, are excluded from revenue in the Condensed Consolidated Statements of Income.

The Company incurs commission expense that is incremental to obtaining contracts with customers. Sales commissions (which are recorded in the "Selling, general and administrative" expense line item in the Condensed Consolidated Statements of Income) are expensed when incurred because such commissions are not owed until the performance obligation is satisfied, which coincides with the end of the contract term, and therefore no remaining period exists over which to amortize the commissions.

The following table presents the Company's revenue disaggregated by geography, based on the billing addresses of its customers (in thousands):

Operating Segment Information

6 Months Ended

Sep. 29, 2018

Segment Reporting [Abstract]

OPERATING SEGMENT INFORMATION

The Company's operating segments as of September 29, 2018 are Mobile Products (MP) and Infrastructure and Defense Products (IDP) based on the organizational structure and information reviewed by the Company's Chief Executive Officer, who is the Company's chief operating decision maker ("CODM"), and these segments are managed separately based on the end markets and applications they support. The CODM allocates resources and assesses the performance of each operating segment primarily based on non-GAAP operating income (loss) and non-GAAP operating income (loss) as a percentage of revenue.

MP is a leading global supplier of cellular radio frequency ("RF") and Wi-Fi solutions for a variety of mobile devices, including smartphones, notebook computers, wearables, tablets, and cellular-based applications for the Internet of Things ("IoT"). Mobile device manufacturers and mobile network operators are adopting new technologies to address the growing demand for data-intensive, increasingly cloud-based distributed applications and for mobile devices with smaller form factors, improved signal quality, less heat and longer talk and standby times. New wireless communications standards are being deployed, and new frequency bands are being added. Carrier aggregation is being implemented to support wider bandwidths, increase data rates and improve network performance. These trends increase the complexity of smartphones, require more RF content and place a premium on performance, integration, systems-level expertise, and product and technology portfolio breadth, all of which are MP strengths. MP offers a comprehensive product portfolio of bulk acoustic wave ("BAW") and surface acoustic wave ("SAW") filters, power amplifiers ("PAs"), low noise amplifiers ("LNAs"), switches, multimode multi-band PAs and transmit modules, RF power management integrated circuits, diversity receive modules, antenna switch modules, antenna tuning and control solutions, modules incorporating PAs and duplexers and modules incorporating switches, PAs and duplexers.

IDP is a leading global supplier of RF solutions with a diverse portfolio of solutions that "connect and protect," spanning communications and defense applications. These applications include high performance defense systems such as radar, electronic warfare and communication systems, Wi-Fi customer premises equipment for home and work, high speed connectivity in Long-Term Evolution ("LTE") and 5G base stations, cloud connectivity via data center communications and telecom transport, automotive connectivity and other IoT, including smart home solutions. IDP products include high power gallium arsenide ("GaAs") and gallium nitride ("GaN") PAs, LNAs, switches, Complementary Metal Oxide Semiconductor ("CMOS") system-on-a-chip solutions, premium BAW and SAW filter solutions and various multi-chip and hybrid assemblies.

The “All other” category includes operating expenses such as stock-based compensation, amortization of intangible assets, acquisition and integration related costs, restructuring charges, start-up costs, gain (loss) on assets and other miscellaneous corporate overhead expenses that the Company does not allocate to its reportable segments because these expenses are not included in the segment operating performance measures evaluated by the Company’s CODM. The CODM does not evaluate operating segments using discrete asset information. The Company’s operating segments do not record intercompany revenue. The Company does not allocate gains and losses from equity investments, interest and other income, or taxes to operating segments. Except as discussed above regarding the “All other” category, the Company’s accounting policies for segment reporting are the same as for the Company as a whole.

The following tables present details of the Company’s reportable segments and a reconciliation of the “All other” category (in thousands):

As a result of the adoption of ASU 2014-09, income related to a right-to-use license of intellectual property was recognized at a point-in-time and, therefore, was included as a transition adjustment impacting retained earnings.

Income Taxes	6 Months Ended
Income Taxes	Sep. 29, 2018
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES U.S. Tax Reform On December 22, 2017, the Tax Cuts and Jobs Act ("Tax Act") was enacted into law. This new law includes significant changes to the U.S. corporate income tax system, including a permanent reduction in the corporate income tax rate from 35% to 21%, full expensing for investments in new and used qualified property, limitations on the deductibility of interest expense and executive compensation, and the transition of U.S. international taxation from a worldwide tax system to a territorial tax system. In December 2017, the SEC staff issued Staff Accounting Bulletin 118 (“SAB 118”), which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC Topic 740 - Income Taxes (“ASC 740”). The provisional tax effects recorded to date will be revised during the measurement period, possibly materially, due to further refinement of the calculations, changes in interpretations and assumptions made, and additional guidance that may be issued by the Department of the U.S. Treasury, the Internal Revenue Service, and other regulatory and standard setting bodies. The Company will complete its analysis within fiscal 2019 consistent with the guidance provided in SAB 118, and any adjustments during this measurement period will be included in net earnings from continuing operations as an adjustment to income tax expense. As described in Note 12 Income Taxes in our 2018 Annual Report on Form 10-K, we were able to reasonably estimate certain effects of the Tax Act provisions that became effective during fiscal 2018 and, therefore, recorded provisional amounts, including a $116.4 million expense related to the one-time transition tax on certain unrepatriated earnings of foreign subsidiaries (the “Transitional Repatriation Tax”) and a $39.1 million benefit from the remeasurement of U.S. deferred tax assets and liabilities. While the Company has not finalized the accounting for the tax effects of the Tax Act, for the six months ended September 29, 2018 we have made a $15.9 million measurement period adjustment to reduce the tax expense related to the previously recorded provisional amounts. This was comprised of an $11.6 million reduction in the Transitional Repatriation Tax and a $4.3 million increase in U.S. deferred tax assets. The Global Intangible Low-Taxed Income (“GILTI”) provisions create a new requirement that certain income earned by foreign subsidiaries be currently included in the gross income of the U.S. shareholder. No provisional adjustments related to the potential GILTI impact on deferred taxes has been made as the Company has not made its accounting policy choice of either: (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred (the “period cost method”) or (2) factoring such amounts into the Company's measurement of its deferred taxes (the “deferred method”). The GILTI and executive compensation limitation provisions in the Tax Act became effective for the Company in fiscal 2019. Provisional estimates for the current year impact of these new provisions are included in the calculation of the fiscal 2019 annual effective tax rate applied to year-to-date income (loss). Income Tax Expense The Company’s provision for income taxes for the three and six months ended September 29, 2018 and September 30, 2017 has been calculated by applying an estimate of the annual effective tax rate for the full fiscal year to “ordinary” income or loss (pre-tax income or loss excluding unusual or infrequently occurring discrete items) to year-to-date income (loss) to determine the amounts for the three and six months ended September 29, 2018 and September 30, 2017. The Company’s income tax expense was $0.8 million and income tax benefit was $31.4 million for the three and six months ended September 29, 2018, respectively, and the Company's income tax benefit was $0.3 million and $9.9 million for the three and six months ended September 30, 2017, respectively. The Company’s effective tax rate was 2.3% and 107.1% for the three and six months ended September 29, 2018, respectively, and (0.7)% and 214.7% for the three and six months ended September 30, 2017, respectively. The Company's effective tax rate for the three and six months ended September 29, 2018 differed from the statutory rate primarily due to tax rate differences in foreign jurisdictions, foreign permanent differences, state income taxes, domestic tax credits generated, changes in unrecognized tax benefits, GILTI, a discrete tax benefit for changes in provisional estimates related to the Transitional Repatriation Tax, and a discrete tax benefit resulting from a retroactive incentive allowing previously non-deductible payments to be amortized. The Company's effective tax rate for the three and six months ended September 30, 2017 differed from the statutory rate primarily due to tax rate differences in foreign jurisdictions, state income taxes, domestic tax credits generated, changes in unrecognized tax benefits, a discrete tax benefit for excess stock compensation deductions in accordance with the new guidance for accounting for employee share-based payments ASU 2016-09, "Compensation - Stock Compensation (Topic 718): Improvements to Employee Share Based Payment Accounting"), and a discrete tax expense, for the six months only, associated with intra-entity transfers in accordance with the new guidance for the intra-entity transfer of assets other than inventory (ASU 2016-16, "Income Taxes (Topic 740), Intra-Entity Transfers of Assets Other Than Inventory"). Deferred Taxes A valuation allowance remained against certain domestic and foreign net deferred tax assets as it is more likely than not that the related deferred tax assets will not be realized. The Company has domestic federal and state tax net operating loss ("NOL") and credit carry-forwards that expire in fiscal years 2019 to 2038 if unused. The use of the NOLs that were acquired in prior year acquisitions is subject to certain annual limitations under Internal Revenue Code Section 382 and similar state income tax provisions. Uncertain Tax Positions The Company’s gross unrecognized tax benefits increased from $122.8 million as of the end of fiscal 2018 to $134.1 million as of the end of the second quarter of fiscal 2019, primarily due to tax positions taken with respect to the current fiscal year.

Consolidating Financial Information [Abstract]

CONSOLIDATING FINANCIAL INFORMATION

CONDENSED CONSOLIDATING FINANCIAL INFORMATION

In accordance with the applicable indentures governing the 2025 Notes and 2026 Notes, the Company's obligations under the 2025 Notes and 2026 Notes are fully and unconditionally guaranteed on a joint and several basis by each Guarantor, each of which is 100% owned, directly or indirectly, by Qorvo, Inc. (the "Parent Company"). A Guarantor can be released in certain customary circumstances.

The following presents the condensed consolidating financial information separately for:


(i)	Parent Company, the issuer of the guaranteed obligations;


(ii)	Guarantor subsidiaries, on a combined basis, as specified in the applicable indenture;


(iii)	Non-guarantor subsidiaries, on a combined basis;


(iv)	Consolidating entries, eliminations and reclassifications representing adjustments to (a) eliminate intercompany transactions between or among the Parent Company, the Guarantor subsidiaries and the non-guarantor subsidiaries, (b) eliminate intercompany profit in inventory, (c) eliminate the investments in the Company’s subsidiaries and (d) record consolidating entries; and


(v)	The Company, on a consolidated basis.

Each entity in the condensed consolidating financial information follows the same accounting policies as described in the consolidated financial statements, except for the use by the Parent Company and Guarantor subsidiaries of the equity method of accounting to reflect ownership interests in subsidiaries that are eliminated upon consolidation. The financial information may not necessarily be indicative of the financial position, results of operations, comprehensive (loss) income, and cash flows, had the Parent Company, Guarantor or non-guarantor subsidiaries operated as independent entities.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Equity Securities without Readily Determinable Fair Value [Policy Text Block]	an equity investment without a readily determinable fair value and is accounted for using the measurement alternative in accordance with ASU 2016-01.
Revenue Recognition Policy	Revenue Recognition Policy The Company generates revenue primarily from the sale of semiconductor products, either directly to a customer or to a distributor, or at completion of a consignment process. Revenue is recognized when control of the promised goods or services is transferred to the Company's customers, in an amount that reflects the consideration it expects to be entitled in exchange for those goods or services. A majority of the Company's revenue is recognized at a point in time, either on shipment or delivery of the product, depending on individual customer terms and conditions. Revenue from sales to the Company’s distributors is recognized upon shipment of the product to the distributors (sell-in). Revenue is recognized from the Company’s consignment programs at a point in time when the products are pulled from consignment inventory by the customer. Revenue recognized for product and services over-time is immaterial (less than 2% of overall revenue). The Company applies a five-step approach as defined in the new standard in determining the amount and timing of revenue to be recognized: (1) identifying the contract with a customer; (2) identifying the performance obligations in the contract; (3) determining the transaction price; (4) allocating the transaction price to the performance obligations in the contract; and (5) recognizing revenue when the corresponding performance obligation is satisfied. Sales agreements are in place with certain customers and contain terms and conditions with respect to payment, delivery, warranty and supply, but typically do not require minimum purchase commitments. In the absence of a sales agreement, the Company’s standard terms and conditions apply. The Company considers a customer's purchase order, which is governed by a sales agreement or the Company’s standard terms and conditions, to be the contract with the customer. The Company’s pricing terms are negotiated independently, on a stand-alone basis. In determining the transaction price, the Company evaluates whether the price is subject to refund or adjustment to determine the net consideration to which the Company expects to be entitled. Variable consideration in the form of rebate programs is offered to certain customers, including distributors. These rebates represent less than 5% of net revenue. The majority of these accruals are classified as a contra accounts receivable. The Company determines variable consideration by estimating the most likely amount of consideration it expects to receive from the customer. The Company's terms and conditions do not give its customers a right of return associated with the original sale of its products. However, the Company may authorize sales returns under certain circumstances, which include courtesy returns and like-kind exchanges. Sales returns are classified as a refund liability. The Company reduces revenue and records reserves for product returns and allowances, rebate programs and scrap allowance based on historical experience or specific identification depending on the contractual terms of the arrangement. The Company’s accounts receivable balance is from contracts with customers and represents the Company’s unconditional right to receive consideration from its customers. Payments are due within one year of completion of the performance obligation and subsequent invoicing and, therefore, do not include significant financing components. To date, there have been no material impairment losses on accounts receivable. Contract assets and contract liabilities recorded on the Condensed Consolidated Balance Sheets were immaterial in the periods presented. The Company invoices customers upon shipment and recognizes revenues in accordance with delivery terms. As of September 29, 2018, the Company had $41.6 million in remaining unsatisfied performance obligations with an original duration greater than one year, of which the majority is expected to be recognized as income over the next twelve months. The Company includes shipping charges billed to customers in "Revenue" and includes the related shipping costs in "Cost of goods sold" in the Condensed Consolidated Statements of Income. Taxes assessed by government authorities on revenue-producing transactions, including tariffs, value-added and excise taxes, are excluded from revenue in the Condensed Consolidated Statements of Income. The Company incurs commission expense that is incremental to obtaining contracts with customers. Sales commissions (which are recorded in the "Selling, general and administrative" expense line item in the Condensed Consolidated Statements of Income) are expensed when incurred because such commissions are not owed until the performance obligation is satisfied, which coincides with the end of the contract term, and therefore no remaining period exists over which to amortize the commissions.
Income Tax Policy	The Company’s provision for income taxes for the three and six months ended September 29, 2018 and September 30, 2017 has been calculated by applying an estimate of the annual effective tax rate for the full fiscal year to “ordinary” income or loss (pre-tax income or loss excluding unusual or infrequently occurring discrete items) to year-to-date income (loss) to determine the amounts for the three and six months ended September 29, 2018 and September 30, 2017.
Fair Value Measurements Policy	The carrying values of cash and cash equivalents, accounts receivable, accounts payable and other accrued liabilities approximate fair values because of the relatively short-term maturities of these instruments.
Operating Segment Policy	The Company's operating segments as of September 29, 2018 are Mobile Products (MP) and Infrastructure and Defense Products (IDP) based on the organizational structure and information reviewed by the Company's Chief Executive Officer, who is the Company's chief operating decision maker ("CODM"), and these segments are managed separately based on the end markets and applications they support. The CODM allocates resources and assesses the performance of each operating segment primarily based on non-GAAP operating income (loss) and non-GAAP operating income (loss) as a percentage of revenue.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Marketable securities are measured at fair value and recorded in "Cash and cash equivalents," "Short-term investments" and "Long-term investments" in the Condensed Consolidated Balance Sheets, and the related unrealized gains and losses are included in "Accumulated other comprehensive loss," a component of stockholders’ equity, net of tax.
