A 73% PAE, Highly Gain Inverse Class-F Power Amplifier for S-Band Applications

Abstract

This paper proposes a continuous-mode inverse Class F power amplifier (PA) achieving wide bandwidth, high output power, and high efficiency. This work includes transmission line-based output/input matching networks and single-ended topology. The main focus of the work is to achieve a high gain with wide bandwidth. The proposed structure incorporates a termination of even and odd harmonics to deliver voltage and current waveform isolation with minimal matching network (MN) design complexities. The analyses simulated in Keysight Technologies Advanced Design System (ADS), which results in a wideband PA design. The results are quantified by using high power-added efficiency (PAE) and output power. PAE of 72.6% and output power more than 41 dBm obtained over wide bandwidth 2–4.2 GHz at −3 dB gain compression. The proposed PA could overcome the traditional performance and utilize for green communication. © 2021, Springer Nature Singapore Pte Ltd.
