RFMD Confirms Guidance for March 2007 Quarter and Provides Preliminary Guidance for June 2007 QuarterPOLARIS™ 3 on Track to Ramp in Second Half of 2007

GREENSBORO, N.C., March 28 /PRNewswire-FirstCall/ -- RF Micro Devices, Inc. (Nasdaq: RFMD), a global leader in the design and manufacture of high- performance radio systems and solutions for applications that drive mobile communications, announced today that it is confirming its revenue and earnings per share guidance for the fourth fiscal quarter ending March 31, 2007, which was originally provided on January 23, 2007. Additionally, the Company announced the achievement of a major milestone-its fiscal year revenue will exceed $1 billion for the first time in the Company's history.

Bob Bruggeworth, president and CEO of RFMD, said, "RFMD will report strong results this fiscal year, with revenue exceeding $1 billion along with significantly improved year-over-year financial performance. Looking ahead to fiscal year 2008, we see growing opportunities in the handset market and the RF semiconductor market in particular. We believe the R&D and other investments we have made and are making in semiconductor technology, communications systems design and manufacturing capacity are positioning us well to capitalize on the accelerating shift in value to the RF-based section of the communications path. There are certainly challenges in the near term as we navigate through product cycles both at RFMD and at our leading customers in the coming quarters. However, we are staying focused on the opportunities for long-term growth of our core business, diversification of our revenue and the realization of manufacturing cost savings from our investments in internal capacity.

"In particular, we remain on track to ramp our Polaris™ 3 transceiver solution in the second half of this calendar year with a large top-tier customer. Also, our POLARIS™ 2 Total Radio module solution has been selected by an existing transceiver customer for the EDGE path of its next- generation WCDMA multimode platform. Our power amplifier business remains healthy, and we see opportunities to expand our industry leadership in both EDGE and WCDMA.

"We will increase investments in our higher margin diversified products in fiscal 2008. GaN products are expected to begin ramping this coming fiscal year and we are already receiving initial orders. WLAN PA revenue grew in the March quarter and is currently expected to grow approximately 200% in fiscal 2008. We also continue to see considerable customer interest in our innovative GPS solution."

Dean Priddy, CFO and vice president of administration of RFMD, stated, "While we'll deliver a solid March quarter and fiscal year 2007, looking into the first quarter of fiscal 2008, we currently anticipate a slowdown in demand from a top tier customer that will impact our operating results. While we are seeing increasing strength with other customers, our customer forecasts in the aggregate currently indicate a sequential decrease in the June quarter, compared to the March quarter, in revenue, margins and earnings per share. We expect to gain greater visibility in the coming weeks and will provide more complete June 2007 quarterly guidance with our April 24, 2007, earnings release and conference call."
