An E-mode GaAs FET power amplifier MMIC for GSM phones

Abstract

An enhancement-mode three stage GaAs FET power MMIC has been developed for single supply portable applications. The MMIC operates fkom a 4.8V power supply and provides over 35 dBm output power from 890-915 MHz with more than 35 dB gain and 47% power added efficiency. Power control range is greater than 70dB. Leakage current is 2uA.
