High-efficiency broadband extended hybrid continuous mode power amplifier with joint input-output harmonic control
Abstract
This paper analyzes the generation mechanism of input harmonics and the inherent contradiction between bandwidth expansion and efficiency degradation in extended continuous mode. It theoretically demonstrates the necessity of implementing input harmonic control and proposes a joint input-output harmonic control technique to compensate for the efficiency sacrificed in extended continuous mode to increase bandwidth, thereby better balancing the efficiency and bandwidth performance of the power amplifier. A 1.6-2.8 GHz high-efficiency broadband extended hybrid continuous power amplifier is designed to verify this theory, with a saturation efficiency of more than 66% and a saturation power of more than 39.8dBm.
