ANAHEIM, Calif., May 26, 2010 (GlobeNewswire via COMTEX News Network) -- RF Micro Devices, Inc. (Nasdaq:RFMD), a global leader in the design and manufacture of high-performance radio frequency components and compound semiconductor technologies, today announced a new family of high linearity, 6-bit digitally controlled variable gain amplifiers (DVGAs). The innovative RFDA family of DVGAs expands RFMD's portfolio of infrastructure grade components that target the cellular base station, point-to-point and CATV end markets.

RFMD's RFDA DVGA product family leverages RFMD's industry leadership in laminate multi-chip modules (MCMs) to integrate high linearity amplifiers from multiple technologies with a digital step attenuator (DSA) and an optional serial to parallel converter. RFMD's DVGA products deliver multi-function features and performance while requiring few external components. As a result, designers of infrastructure transceivers can design radios with smaller size, higher assembly yields and lower cost. RFMD's DVGA integration path also supports future market trends toward smaller base station sizes, microcells, and remote radio heads for new infrastructure deployments.

The RFDA product family offers a selection of components with gain up to 38dB, OIP3 up to 43dBm and a maximum operating frequency up to 4GHz. The family includes wideband and narrowband versions, covering all 2G, 3G and 4G (LTE and WiMAX) standards for base station frequency bands. The components are suitable for both receiver and transmitter designs and are offered in both parallel and serial interface versions.

Availability and Pricing
The RFDA DVGA product family is immediately available in mass production quantities. Pricing is available upon request by contacting an RFMD sales representative or by visiting www.rfmd.com/purchase.
