摘要

E类放大器在理想情况下提供接近100%的高效率。本文介绍了一种减少宽带并联电路E类功率放大器二次谐波的拓扑结构。功率工作大于5.5W时，漏极效率> 60%，宽带宽(134-174MHz)的二次谐波< 40dBm。

Second harmonic reduction in broadband HF/VHF/UHF class E RF power amplifiers

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.
