Abstract
Class E amplifier offers high efficiency approaching 100% for ideal case. This paper describes a topology to reduce second harmonic in a broadband parallel circuit class E power amplifier (PA). Drain efficiency > 60% and second harmonic < 40dBm across wide bandwidth (134–174MHz) is shown at power operation more than 5.5W.
