A 100W Class-E GaN HEMT with 75% Drain Efficiency at 2GHz

Abstract

A 100W class-E GaN HEMT device has been developed for high power and high efficiency amplifier. The authors achieved superior measurement results; drain efficiency of 75%, CW output power of 100W and associated power gain of 12dB at 2.14GHz and 50V drain bias operation with acceptable frequency band characteristics in simple class-E circuit topology
