A Zero-Voltage-Switching Contour-Based Outphasing Power Amplifier

Abstract

A parallel class-E modified Chireix outphasing power amplifier (PA) that can maintain high efficiency across a wide output power range is presented. The architecture presented essentially implements a zero voltage switching (ZVS) contour-based PA using a modified Chireix outphasing structure. It utilizes the inherent load modulation present in the… (More)
