A 1.2 W, 60% efficient power amplifier IC for commercial applications

Abstract

A 1.2 Watt, 6 V, 60% efficient, dual bias power amplifier GaAs IC operating in the AMPS (Advanced Mobile Phone service) band of 824 MHz to 849 MHz has been demonstrated. The IC is a two stage, class AB biased amplifier that has 24 dB of power gain. The input return loss is 12 dB over the band. The IC is packaged in a SOIC 16-pin plastic package that measures 30 mm/sup 2/.
