RFMD goes back to base with latest amplifiers
High-Linearity Digitally-Controlled Variable Gain Amplifiers (DVGAs) suited to wireless infrastructure applications such as cellular base stations.
RF Micro Devices is marketing a new family of high linearity, 6-bit digitally controlled variable gain amplifiers (DVGAs). The latest RFDA family of DVGAs targets the cellular base station, point-to-point and CATV end markets.
The RFDA DVGA product family comes in laminate multi-chip modules (MCMs) and can integrate high linearity amplifiers with a digital step attenuator (DSA) and an optional serial to parallel converter.
Delivering multiple functions and requiring few external components, developers of infrastructure transceivers can design smaller and cheaper radios with higher assembly yields.
The DVGA integration path also supports future market trends toward smaller base station sizes, microcells, and remote radio heads for new infrastructure deployments.
A selection of components are available with gains of up to 38dB, OIP3 up to 43dBm and a maximum operating frequency up to 4GHz. The wideband and narrowband versions cover 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.
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 .
