摘要
采用容性耦合匹配结构,基于0.1μm GaAs pHEMT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15.5 dB, 功率约20 dBm.这一结果证明了这种设计方法的有效性.
Abstract
Adopting the capacitive coupled matching structure, a Ka-band wideband three-stage power amplifier (PA) MMIC was designed by 0.1μm GaAs pHEMT 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 upon 30% over 32~40 GHz with 20 dBm output power and more than 15.5 dB power gain, which demonstrates the effectiveness of this design skill.
