摘要
采用容性耦合匹配结构,基于0.1μm GaAs pH EMT工艺设计了一个Ka波段三级宽带功率放大器MMIC.为了辅助宽带功放设计,提出了一组公式来分析这一匹配结构.在展示的功放中,此结构同时实现了宽频带和高效率.功放处于饱和状态时,测得在32～40 GHz频率范围内的PAE大于30%,功率增益超过15.5dB,功率约20 dB m.这一结果证明了这种设计方法的有效性.
Adopting the capacitive coupled matching structure,a Ka-band wideband three-stage power amplifier（PA） MMIC was designed by 0. 1μm GaA s pH EMT process in this paper. To facilitate the design of wideband PA,a set of formulas was proposed to analyze this matching structure. This structure achieves wide operating band and high power-added efficiency（ PAE） simultaneously in the presented PA. The measured saturation PAE is upon30% over 32 ～ 40 GHz with 20 dB m output power and more than 15. 5 dB power gain,which demonstrates the effectiveness of this design skill.
