It is housed in an industry standard 3 mm PQFN package and operates from a single 3.3 V bias. The chip includes a power amplifier, transmit/receive switch, power detector, switched attenuators, bias circuits and digital control circuitry. The transmit path includes two 3 dB switched attenuators and a power detector for gain adjustment and linearity optimization. A switched attenuator in the receiver provides a 15 dB gain step. The integrated bias circuit stabilizes transmit amplifier performance over temperature and process variation with optional bias adjustment. The device typically delivers 20 dBm at P1dB and +32 dBm OIP3 across the operating temperature range. The digital inputs control all circuit operating modes and are compatible with Entropic’s MoCA chipsets.
