摘要
Abstract
In this paper,in order to solve the problem of low efficiency of traditional wideband high-power amplifier,a new type of resistive reactance continuous B/J power amplifier mode is adopted to expand the output load impedance space of transistor with high efficiency.As a result,the drain stage output efficiency of broadband power amplifier is improved.Then,a balanced power amplifier(PA)based on 0.25µm gate-length GaN HEMT is proposed.The PA combines LC matching network and Chebyshev impedance converter to realize broadband input and output impedance matching of GaN HEMT device,and utilizes a 3 dB Lange coupler to achieve broadband balanced power combination.Under the operating condition of continuous wave(CW),the proposed balanced PA has an output power greater than 100 W,drain efficiency greater than 45%,power gain greater than 9 dB,and anti-load mismatch better than 5:1 in the frequency range of 2 GHz to 6 GHz.关键词
