Generalized Class-E Power Amplifier with Shunt Filter at Any Duty Ratio

Abstract

This paper introduces an analytical design method for the generalized Class-E power amplifier (PA) with shunt filter at any duty ratio. The idealized switch waveforms are derived first, and then the optimal parameter values of load network are obtained, and three important indicators the peak switch drain voltage, power output capability and maximum operating frequency at different sets of values are also investigated. To verify the effectiveness of the design method, a simulation experiment is demonstrated showing waveforms matching well with theory.
