The GSM850/900 and DCS/PCS power amplifier blocks including power control are combined with a low insertion loss dual-band pHEMT switch, Tx harmonics filtering, integrated switch decoder, two receive ports, and ESD protection. This architecture eliminates the need for any PA-toswitch design effort for phone designers. Both Rx ports are frequency independent and allow flexible routing to the transceiver. Fabricated in high-reliability InGaP HBT /pHEMT technology, the module supports GPRS class 1...
