Description
M/A-COM's MAAPSS0006 is a high power, high efficiency linear power amplifier in a miniature FQFP-N 4mm plastic package. The MAAPSS0006 includes a 2-stage amplifier and bias control network. Efficiency of the MAAPSS0006 is optimized for each mode by an on-chip analog control circuit. The MAAPSS0006 is ideally suited for CDMA and AMPS handset applications where high linearity and low power consumption are important transmitter requirements. The MAAPSS0006 is design to operate with the MD59-0054 Upconverter/Driver IC. 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.
