RFMD introduces new family of DVGAs

RF Micro Devices (RFMD) Inc of Greensboro, NC, USA has introduced a new family of high linearity, 6-bit digitally controlled variable gain amplifiers (DVGAs), which expand the firm’s portfolio of infrastructure grade components that target the cellular base station, point-to-point and CATV end markets.

RFMD says that its new RFDA DVGA product family leverages the firm’s industry leadership in laminate multi-chip modules to integrate high linearity amplifiers from multiple technologies with a digital step attenuator (DSA) and an optional serial to parallel converter. RFDA 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, says RFMD. 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.
