Design of a 0.3~3.5 GHz Hybrid Continuous Power Amplifier

Abstract

Compared with the traditional continuous model, the mixed continuous model weakens the impedance condition and simplifies the difficulty of broadband matching. In this paper, a new type of harmonic control network used a hybrid continuous model and based on the concept of impedance buffering is designed to design a hybrid continuous radio frequency power amplifier that spans three octave layers. The measured results show that the drain efficiency is 58.4%~72.6%, the gain is more than 10 dB, and the output power is 39.8~41.2 dBm in the frequency range of 168.4% relative bandwidth of 0.3~3.5 GHz.
