Abstract

—Harmonic reflections primarily influence the per formance of class-F power amplifiers, particularly when imple mented in practice, with non-ideal lossy components. To ana lyze these limitations, the impedance transformation capabilities of harmonic reflection networks is compared between lumped elements and transmission lines, using S-parameters of real components and substrate parameters, respectively. A mixed network of lumped elements and transmission lines is introduced and validated through the design and implementation of a 10W class-F power amplifier operating at 144MHz. Measurements demonstrate a peak efficiency of 75.9% at 20.39dB gain. The results conclude a practical design methodology for selecting suitable harmonic termination networks based on frequency and implementation constraints.
