Abstract

ABSTRACT: This paper aims to design and fabricate a class-F −1 power amplifier (PA) to act at 2.4 GHz frequency with high power-added efficiency (PAE). For this purpose, a harmonic control network is introduced, which consists of three parts: a harmonic control circuit, a transistor bias circuit, and a suppression circuit. Each part of the harmonic control network is individually designed and finally, they are optimised together in the final amplifier circuit. The fabricated PA results mimic the simulation one. The presented PA has functional specifications like high PAE, the ability to control the second and third harmonics, and a low drain voltage supply of 2.2 V. Due to these excellent features, this PA is suitable for wireless applications.
