A GaN HEMT Class-F amplifier for UMTS/WCDMA applications

In this work, the authors present a highly efficient GaN HEMT Class-F amplifier designed for Universal Mobile Telecommunications Systems using Wideband Code Division Multiple Access (UMTS/WCDMA). The amplifier has a peak PAE of 76% with an output power of 10.5 W. A comparison between class-F and inverse Class-F was also made.
