摘要：

This paper introduces a new wide bandwidth Class E power amplifier providing high order harmonic suppression circuit. A design technique is presented on the methodology to achieve wideband high efficiency performance while preserving high harmonic suppression. A prototype board demonstrated drain efficiency of 70% and second harmonic rejection of more than 84 dBc (as well as higher harmonics), and output power level more than 6.5W with +/- 0.5 dB power flatness, across VHF band (136-174 MHz). Simulations of power performance (i.e. efficiency and output power) were verified by measurements, and good agreements were obtained.
