Abstract :
In this paper, we report on the design and evolution of a 500 W, 27 MHz Class E amplifier. It doubles the operating frequency of previous high efficiency amplifiers using MOSFET transistors in the TO-247 package. Device criteria, circuit design, and amplifier performance characteristics are presented and compared to a HEPA computer model.
