Abstract
A high-efficiency GaAs FET power amplifier having a total efficiency of 70% and an output power of 2 W is realised in the 900 MHz band. A drain efficiency of 80% was achieved at a low operation voltage of 6 V. These high efficiencies were obtained by using the even-order harmonic tuning of an output matching circuit. Important parameters for achieving this efficiency are also clarified.Keywords
