High-frequency Class-E power amplifier with shunt filter

Abstract

In this paper, an experimental investigation of high-frequency Class-E power amplifier with shunt filter is presented. Using of a shunt LC filter in the load network instead of a series LC tank used in conventional Class-E power amplifier allows the maximum operating frequency and second-harmonic suppression level to be increased compared to conventional Class-E power amplifier. The parasitic resistive elements of the load network were taken into account in simulation of Class-E power amplifier with shunt filter and contribution of each parasitic resistive element has been simulated and calculated.
