Abstract
A quad-band GSM/GPRS power amplifier module is designed with a built-in ability of RF power transmitting control. Within the RF power transmitting control loop, a RF power detecting circuit with another reference circuit are embedded together onto the same InGaP/GaAs HBT power amplifier chip to achieve a good temperature compensation. Such power chips are then assembly with a silicon CMOS comparative chip by the multi-chip module technology and functions as a closed- loop power controlled GSM/GPRS power amplifier module. It had successfully demonstrated as play for all quad-band operations (GSM850, EGSM900, DCS1800, PCS1900).
