MAAPSS0003 Preliminary PCS TDMA/CDMA Power Amplifier 1750 - 1910 MHz GND VCC2 GND High Gain 2-stage HBT Amplifier Single Supply, 3V Operation 29dBm Linear Output Power High Efficiency Low Quiescent Current Operates in US and Korean PCS Bands Miniature FQFP-N 4mm Plastic Package VCC1 20 GND Description 1 GND GND RFOUT RFIN RFOUT GND GND Bias Network M/A-COM’s MAAPSS0003 is a high power, high efficiency linear power amplifier in a miniature FQFP-N 4mm plastic package. The MAAPSS0003 includes a 2-stage amplifier and bias control network. Analog signals control output power and power-off for active and standby modes. The MAAPSS0003 is fabricated using M/A-COM’s iHBT HBT process. The process utilizes the InGaP/GaAs materials system for reduced performance variation over temperature, high reliability and improved manufacturability. VPD2 VMODE GND BIAS GND The MAAPSS0003 is ideally suited for TDMA and CDMA handset applications where high linearity and low power consumption are important transmitter requirements. The MAAPSS0003 is design to operate with the MD59-0062 Upconverter/Driver IC.
