Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES	BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES On February 22, 2014, RF Micro Devices, Inc. ("RFMD") and TriQuint Semiconductor, Inc. ("TriQuint") entered into an Agreement and Plan of Merger and Reorganization (as subsequently amended on July 15, 2014, the "Merger Agreement") providing for the business combination of RFMD and TriQuint ("Business Combination") under a new holding company named Qorvo, Inc. (formerly named Rocky Holding, Inc.) ("Qorvo"). The Business Combination closing was effective on January 1, 2015 (fourth quarter of fiscal 2015). For financial reporting and accounting purposes, RFMD was the acquirer of TriQuint. The results presented in the Condensed Consolidated Financial Statements, the Notes to the Condensed Consolidated Financial Statements and in the Management's Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") reflect those of RFMD prior to the completion of the Business Combination with TriQuint on January 1, 2015 and those of Qorvo subsequent to the completion of the Business Combination. As used herein, all references to "the Company," "we," "us" and "our" prior to January 1, 2015 refer to RFMD and all such references on or after January 1, 2015 refer to Qorvo. The accompanying Condensed Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States. 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 accounting principles generally accepted in the United States 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 Qorvo’s audited consolidated financial statements and notes thereto included in Qorvo’s Annual Report on Form 10-K for the fiscal year ended March 28, 2015. 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 2016 is a 53-week year and fiscal 2015 was a 52-week year, however, the first quarters of both fiscal 2016 and fiscal 2015 included 13 weeks.

Earnings Per Share [Abstract]

NET INCOME PER SHARE

Pursuant to the terms of the Merger Agreement, effective January 1, 2015, the Company effected a one-for-four reverse stock split of the Company's issued and outstanding shares of common stock. All share and per share information contained in the accompanying Condensed Consolidated Financial Statements, Notes to the Condensed Consolidated Financial Statements and the MD&A have been retroactively adjusted to reflect the reverse stock split for all periods presented.

The following table sets forth a reconciliation of the numerators and denominators in the computation of basic and diluted net income per share (in thousands, except per share data):



	Three Months Ended
	June 27, 2015		June 28, 2014
Numerator:
Numerator for basic and diluted net income per share — net income available to common stockholders	$	2,036	$	38,647
Denominator:
Denominator for basic net income per share — weighted average shares	149,322		71,564
Effect of dilutive securities:
Stock-based awards	5,139		2,095
Denominator for diluted net income per share — adjusted weighted average shares and assumed conversions	154,461		73,659
Basic net income per share	$	0.01	$	0.54
Diluted net income per share	$	0.01	$	0.52

In the computation of diluted net income per share for the three months ended June 27, 2015 and June 28, 2014, outstanding stock options to purchase less than 0.1 million shares were excluded because the exercise price of the options was greater than the average market price of the underlying common stock and the effect of their inclusion would have been anti-dilutive.

The computation of diluted net income per share for the three months ended June 28, 2014 does not assume the conversion of the Company’s previously issued $175 million initial aggregate principal amount of convertible subordinated notes (the "2014 Notes"). The 2014 Notes became due on April 15, 2014, and the remaining principal balance of $87.5 million was paid with cash on hand.

Debt	3 Months Ended
Debt	Jun. 27, 2015
Debt Disclosure [Abstract]
DEBT	DEBT Credit Agreement On April 7, 2015, the Company and certain material domestic subsidiaries of the Company (the “Guarantors”) entered into a five-year unsecured senior credit facility 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”). The Credit Agreement includes a $300.0 million revolving credit facility, which includes a $25.0 million sublimit for the issuance of standby letters of credit and a $10.0 million sublimit for swingline loans. The Company may request, at any time and from time to time, that the revolving credit facility be increased by an amount not to exceed $150.0 million. The revolving credit facility is available to finance working capital, capital expenditures and other lawful corporate purposes. The Company’s obligations under the Credit Agreement are jointly and severally guaranteed by the Guarantors. The Company currently has no outstanding amounts under the Credit Agreement. At the Company’s option, loans under the Credit Agreement shall bear interest at (i) the Applicable Rate (as defined in the Credit Agreement) plus the Eurodollar Rate (as defined in the Credit Agreement) or (ii) the Applicable Rate plus a rate equal to the highest of (a) the federal funds rate plus 0.50%, (b) the prime rate of the Administrative Agent, or (c) the Eurodollar Rate plus 1.0% (the “Base Rate”). All swingline loans will bear interest at a rate equal to the Applicable Rate plus the Base Rate. The Eurodollar Rate is the rate per annum equal to the London Interbank Offered Rate, as published by Bloomberg, for dollar deposits for interest periods of one, two, three or six months, as selected by the Company. The Applicable Rate for Eurodollar Rate loans ranges from 1.50% per annum to 2.00% per annum. The Applicable Rate for Base Rate loans ranges from 0.50% per annum to 1.00% per annum. Interest for Eurodollar Rate loans shall be payable at the end of each applicable interest period or at three-month intervals, if such interest period exceeds three months. Interest for Base Rate loans shall be payable quarterly in arrears. The Company will pay a letter of credit fee equal to the Applicable Rate multiplied by the daily amount available to be drawn under any letter of credit, a fronting fee, and any customary documentary and processing charges for any letter of credit issued under the Credit Agreement. 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, including financial covenants that the Company must maintain a consolidated leverage ratio not to exceed 2.50 to 1.0 as of the end of any fiscal quarter of the Company and a consolidated interest coverage ratio not to be less than 3.00 to 1.0 as of the end of any fiscal quarter of the Company. The Credit Agreement also contains customary events of default, and the occurrence of an event of default will increase the applicable rate of interest by 2.00% and could result in the termination of commitments under the revolving credit facility, the declaration that all outstanding loans are due and payable in whole or in part and the requirement of cash collateral deposits in respect of outstanding letters of credit. Outstanding amounts are due in full on the maturity date of April 7, 2020 (with amounts borrowed under the swingline option due in full no later than ten business days after such loan is made). Convertible Debt In April 2007, the Company issued $175 million aggregate principal amount of 1.00% convertible subordinated notes due 2014 These notes became due on April 15, 2014, and the remaining principal balance of $87.5 million plus interest of $0.4 million was paid with cash on hand.

Income Taxes	3 Months Ended
Income Taxes	Jun. 27, 2015
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES Income Tax Expense The Company’s provision for income taxes for the three months ended June 27, 2015 and June 28, 2014 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) for the three months ended June 27, 2015 and June 28, 2014. The Company’s income tax expense was $0.6 million for the three months ended June 27, 2015 and $7.4 million for the three months ended June 28, 2014. The Company’s effective tax rate was 22.5% for the three months ended June 27, 2015 and 16.1% for the three months ended June 28, 2014. The Company's effective tax rate for both the first quarter of fiscal 2016 and the first quarter of fiscal 2015 differed from the statutory rate primarily due to tax rate differences in foreign jurisdictions, state income taxes, domestic tax credits generated, adjustments to deferred tax assets and liabilities, adjustments to the valuation allowance limiting the recognition of the benefit of domestic deferred tax assets, changes in uncertain tax position exposure, and the domestic production activity deduction. Deferred Taxes The valuation allowance against net deferred tax assets has increased in the first quarter of fiscal 2016 by $1.4 million from the $13.8 million balance as of the end of fiscal 2015, with the change primarily arising from an increase in domestic deferred tax assets related to domestic state tax credits. 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 outstanding domestic federal and state tax net operating loss (“NOLs”) carry-forwards that expire in fiscal years 2016 to 2035 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 tax provisions. Uncertain Tax Positions The Company’s gross unrecognized tax benefits decreased from $59.4 million as of the end of fiscal 2015 to $58.9 million as of the end of the first quarter of fiscal 2016, with the change arising from a $0.2 million increase related to tax positions taken with respect to the current fiscal year and a $0.7 million decrease related to tax positions taken with respect to prior fiscal years.

The estimated fair value of available-for-sale securities was based on the prevailing market values on June 27, 2015 and March 28, 2015. We determine the cost of an investment sold based on the specific identification method.

There were $4.0 million of gross realized gains and no gross realized losses recognized on available-for-sale securities for the three months ended June 27, 2015. The gross realized gains and losses recognized on available-for-sale securities for the three months ended June 28, 2014 were insignificant.

Unrealized losses on available-for-sale investments in a continuous unrealized loss position for fewer than 12 months as of June 27, 2015 and March 28, 2015 were insignificant. No available-for-sale investments were in a continuous unrealized loss position for 12 months or greater as of June 27, 2015 or as of March 28, 2015.

The aggregate amount of available-for-sale securities in an unrealized loss position at June 27, 2015 was $85.5 million with $0.3 million in unrealized losses. The aggregate amount of available-for-sale securities in an unrealized loss position at March 28, 2015 was $112.9 million with $0.4 million in unrealized losses.

The amortized cost of available-for-sale investments in debt securities with contractual maturities is as follows (in thousands):



	June 27, 2015				March 28, 2015
	Cost		Estimated Fair Value		Cost		Estimated Fair Value
Due in less than one year	$	304,732	$	304,737	$	289,641	$	289,615

Total investments in debt securities	$	306,882	$	306,589	$	291,791	$	291,365

Fair Value Measurements

On a quarterly basis, the Company measures the fair value of its marketable securities, which are comprised of U.S. government/agency securities, corporate debt, auction rate securities (ARS), marketable equity securities, and money market funds. Marketable securities are reported at fair value in cash and cash equivalents, short-term investments and long-term investments on the Company’s Condensed Consolidated Balance Sheet. The related unrealized gains and losses are included in "Accumulated other comprehensive income 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 June 27, 2015 and March 28, 2015 (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) Corporate debt includes corporate bonds and commercial paper which are valued using observable market prices for identical securities that are traded in less active markets.

(3) The 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 asset 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.

Other Fair Value Disclosures

The carrying values of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate fair values because of the relatively short-term maturities of these instruments.

RECENT ACCOUNTING PRONOUNCEMENTS	RECENT ACCOUNTING PRONOUNCEMENTS In April 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2015-03, "Interest - Imputation of Interest (Topic 835-30): Simplifying the Presentation of Debt Issuance Costs ("ASU 2015-03"). ASU 2015-03 requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the related debt liability's carrying value, which is consistent with the presentation of debt discounts. The Company adopted the provisions of ASU 2015-03 in the first quarter of fiscal 2016 and the adoption of this standard is not expected to have a material impact on the Company's consolidated financial statements. Due to the absence of authoritative guidance within ASU 2015-03 for debt issuance costs related to revolving debt arrangements, the Company will continue to capitalize such costs as an asset and amortize them ratably over the term of the revolving debt arrangement. In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers" ("ASU 2014-09") that amends existing guidance on revenue recognition. The new guidance is based on principles that an entity will recognize revenue to depict the transfer of goods and services to customers at an amount the entity expects to be entitled to in exchange for those goods and services. The guidance requires additional disclosures regarding the nature, amount, timing, and uncertainty of cash flows and both qualitative and quantitative information about contracts with customers and applied significant judgments. In July 2015, the FASB deferred the effective date for the adoption of ASU 2014-09 by one year. Early adoption is permissible but not before its original effective date of annual reporting periods beginning after December 15, 2016. The new authoritative guidance will become effective for the Company in the first quarter of fiscal 2019, using one of two retrospective methods of adoption. The Company has not determined which method it will adopt and is evaluating the effects the new guidance will have on its consolidated financial statements.

Segment Reporting [Abstract]

OPERATING SEGMENT INFORMATION

The Company’s operating segments as of June 27, 2015 are Mobile Products (MP) and Infrastructure and Defense Products (IDP). In the fourth quarter of fiscal 2015, the Company renamed its reportable segments from Cellular Products Group (CPG) to MP, and Multi-Market Products Group (MPG) to IDP, as a result of the Business Combination. Additionally, the chief operating decision maker (CODM) elected to discontinue reporting Compound Semiconductor Group (CSG) as an operating segment.

MP is a leading global supplier of radio frequency (RF) solutions that perform various functions in the cellular radio front end section of smartphones, tablets and other mobile devices. These RF solutions are required for devices that operate under 4G, Wi-Fi and other communications standards. These solutions include various discrete RF components and module configurations, including complete RF front end modules that combine high-performance filters, power amplifiers and switches into single placement solutions.

IDP is a leading global supplier of a broad array of RF solutions to wireless network infrastructure, defense and aerospace markets and short-range connectivity applications for commercial, consumer, industrial and automotive markets. IDP’s solutions include high power gallium arsenide ("GaAs") and gallium nitride ("GaN") components and various multichip and hybrid assemblies.

As of June 27, 2015, MP and IDP are separate reportable segments based on the organizational structure and information reviewed by the Company's Chief Executive Officer, who is the Company's CODM, and 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.

The “All other” category includes operating expenses such as stock-based compensation, amortization of purchased intangible assets, acquisition and integration related costs, intellectual property rights (IPR) litigation costs, restructuring and disposal costs, certain consulting costs, 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 inter-company 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):

Business Acquisition	3 Months Ended
Business Acquisition	Jun. 27, 2015
Business Combinations [Abstract]
BUSINESS ACQUISITION	BUSINESS ACQUISITION Effective January 1, 2015, pursuant to the Merger Agreement, RFMD and TriQuint completed a strategic combination of their respective businesses through the “merger of equals” Business Combination under a new holding company named Qorvo, Inc. As a result of the Business Combination, RFMD and TriQuint have combined complementary product portfolios, featuring power amplifiers (PAs), power management integrated circuits (PMICs), antenna control solutions, switch-based products and premium filters, to deliver a comprehensive portfolio of high-performance mobile solutions. It is expected that the Business Combination will continue to strengthen the combined company’s service to the infrastructure and defense/aerospace industries and enable advanced gallium nitride (GaN) solutions for additional markets and applications. It is also expected that customers will benefit from new scale advantages in manufacturing and research and development, as well as an aggressive roadmap of new products and technologies. The total estimated purchase price was approximately $5,254.4 million. The allocation of the purchase price reflected in the accompanying financial statements is preliminary and is based upon estimates and assumptions that are subject to change within the measurement period (up to one year from the acquisition date pursuant to ASC 805). The measurement period remains open pending the completion of procedures related to deferred taxes. The Business Combination resulted in the recognition of $470.0 million of in-process research and development (IPRD) of which $350.0 million relates to the MP operating segment and $120.0 million relates to the IDP operating segment. The IPRD encompasses a broad technology portfolio of product innovations in RF applications for MP and IDP. These technologies include a variety of semiconductor processes in GaAs and GaN for power and switching applications and surface acoustic wave (SAW) and bulk acoustic wave (BAW) structures for filter applications. Included in IPRD are continuous improvements in the process for design and manufacturing as well as innovation in fundamental research areas such as materials, simulation and modeling, circuit design, device packaging and test. As of June 27, 2015, the IPRD for the MP operating segment was 58% complete with an estimated completion time of approximately 9 months and a remaining cost to complete of approximately $25.2 million. As of June 27, 2015, the IPRD associated with the IDP operating segment was 77% complete with an estimated completion time of approximately 6 months and a remaining cost to complete of approximately $33.9 million. Upon completion of the development, acquired IPRD assets will be transferred to finite-lived intangible assets and amortized over their useful lives. During the first quarter of fiscal 2016, the Company incurred integration costs of approximately $10.4 million and restructuring costs of approximately $2.9 million (including stock-based compensation) associated with the Business Combination. During the first quarter of fiscal 2015, the Company incurred acquisition costs of $2.5 million and integration costs of $6.0 million associated with the Business Combination. The acquisition, integration and restructuring costs are being expensed as incurred and are presented in the Condensed Consolidated Statements of Income as "Other operating expense."

Subsequent Event	Jun. 27, 2015
Subsequent Events [Abstract]
SUBSEQUENT EVENT	SUBSEQUENT EVENT On August 4, 2015, Qorvo's wholly-owned subsidiary TriQuint invested $25.0 million to acquire shares of Series F Preferred Stock of Cavendish Kinetics Limited, a private limited company incorporated in England and Wales (“Cavendish”). In connection with this investment, TriQuint, Cavendish and certain Cavendish shareholders and option holders entered into an agreement (the “Acquisition Agreement”) under which Cavendish and certain of its shareholders and option holders granted TriQuint the exclusive option and right, but not the obligation, to acquire the entire issued capital of Cavendish on the terms and conditions in the Acquisition Agreement. TriQuint may exercise the option at any time until the earlier of: (i) 60 days after Cavendish’s pre-production release of a specified product and (ii) June 30, 2017, unless earlier terminated in accordance with its terms. This option period may be extended until June 30, 2018 under certain conditions, including an additional investment in Cavendish by TriQuint of up to $25.0 million. The purchase price for Cavendish would be determined based upon a total valuation of Cavendish on a debt-free, cash-free basis, equal to $300.0 million, plus an amount equal to 4.5 times Cavendish’s annualized legacy product revenue (with a proportionate reduction to reflect TriQuint’s ownership in Cavendish at the time of purchase). The Acquisition Agreement contains customary representations, warranties, indemnities and covenants of the parties.

Basis of Presentation and Significant Accounting Policies (Policies)	3 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Income Tax Policy	The Company’s provision for income taxes for the three months ended June 27, 2015 and June 28, 2014 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) for the three months ended June 27, 2015 and June 28, 2014
Fair Value Measurements Policy	On a quarterly basis, the Company measures the fair value of its marketable securities, which are comprised of U.S. government/agency securities, corporate debt, auction rate securities (ARS), marketable equity securities, and money market funds. Marketable securities are reported at fair value in cash and cash equivalents, short-term investments and long-term investments on the Company’s Condensed Consolidated Balance Sheet. The related unrealized gains and losses are included in "Accumulated other comprehensive income loss", a component of stockholders’ equity, net of tax.
Operating Segment Policy	As of June 27, 2015, MP and IDP are separate reportable segments based on the organizational structure and information reviewed by the Company's Chief Executive Officer, who is the Company's CODM, and 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.
