Abstract

Class E amplifier offers high efficiency aproaching 100% for an ideal case. This paper introduces a first practical implementation of a broadband Class E design combining a parallel circuit load network with reactance compensation technique. The novel broadband class E parallel circuit with reactance compensation has been investigated theoretically and experimentally. An efficient method of simulation technique using Harmonic Balance to predict the class E performance is presented as well. In measurement level, the drain efficiency of 74 % at operating power of 8 W and power flatness of 0.7 dB are achieved across bandwidth of 135 to 175 MHz with supply voltage of 7.2 V. Simulations were verified by measurements and good agreement was obtained.
