Abstract :
A 3-stage GaAs FET power amplifier MMIC utilizing a quasi-enhancement mode PHEMT process has been developed for single supply GSM applications. The MMIC operates from a 3.2 V power supply and at 900 MHz, provides 35.5 dBm output power and 63.0% power added efficiency. Another 3 stage MMIC designed for DCS-1800, which at 1750 MHz provides 33.2 dBm output power with 61.1% PAE, is also presented.
