Abstract

<p>  This paper describes a unified design theory both for high-efficiency power amplifiers and high-efficiency rectifiers base on the time reversal duality principle. In high efficiency power amplifier design, optimization for time domain drain voltage and drain current waveforms can be transformed into load impedance optimization problem, where DC input power and RF output power at fundamental frequency are balanced by nulling harmonic output power. Class-F and Class-R (Reactive harmonic load) amplifiers are their good examples. These high-efficiency power amplifiers can be used as rectifiers with appropriate gate switch timing. Using this principle, a developed GaN-HEMT smart module which can be used both as a high-efficiency power amplifier and a high-efficiency rectifier is demonstrated.</p>
