Performance comparison of class E RF power amplifier with different load netwok configuration

摘要

Class E power amplifier circuit consists mainly of active device operates as a switch, load network and series LC filter tuned to fundamental frequency. Class E power amplifier has different configurqations according to the load network such as: class E power amplifier with shunt capacitance, with parallel tuned circuit and with shunt inductance. The aim of this paper is to compare using simulation between the amplifier performances such as PAE, gain, drain voltage and current waveforms for the three configurations of class E power amplifier at different frquencies of operation.
