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 <; 40 dBm across wide bandwidth (134-174 MHz) is shown at power operation more than 5.5 W.
