Abstract

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 configurations 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 frequencies of operation.
