Abstract

The high efficiency of the saturation state and rollback state is an important part of the front end of modern wireless communication systems. Improving the efficiency of RF power amplifiers is of great significance for energy saving and amplifier performance. Based on the traditional Doherty power amplifier, the harmonic suppression network is introduced before the fundamental frequency matching, so that the second harmonic impedance and third harmonic impedance can achieve continuous class F impedance matching conditions, and then the saturation efficiency and regression efficiency can be improved without affecting the fundamental wave matching. The results of the simulation show that the saturation efficiency of the Doherty amplifier reaches 73.94%~77.22%. The drain efficiency of back-off 6 dB reaches 61.80%~62.92%. The average saturation drain efficiency is 75.58%, and the average back-off 6 dB drain efficiency is 62.36%.
