An adaptive self-biased class-e power amplifier

Abstract

As the rapid development of 5G system and wireless communication technology, communication systems emphasize more on high-speed and stable information transmission and energy consumption, which directly promotes the update iteration of RF hardware design. As an energy-consuming device and the last stage device of the transmitter, the power amplifier determines the overall performance of the transmitter system. Theoretically, the class E power amplifier can reach 100% efficiency, the energy utilization rate is high, and it has the advantages of simple structure. Therefore, in the environment of highly integrated design and rapid development of mobile devices, Class E power amplifiers with high efficiency have gradually attracted people's attention.
