Abstract

. Power efficiency is a critical element in the design of RF power amplifiers for contemporary wireless applications. Improved power efficiency results in longer battery life, less heat dissipation needs, a more compact design, and increased dependability. A high-efficiency Amplifier with class-E power is described in this article, which is based on a GaAs transistor and is optimized for operation in the 1.8 GHz LTE band. It is possible to improve the efficiency and output power of a transmission line-based output network by decreasing the harmonic powers of the transmission lines. It is found that all harmonic level values down than -90 dBc were suppressed by the proposed class-E amplifier. With a 7-dB increase in output power, the peak power-added efficiency (PAE) is 82 percent at 30 dBm output power, resulting in a power gain of 82 percent.
