摘　　要：现今通信设备对于硬件设备的小型化、全国产化要求越来越严格,为了全面提升通信设备的小型化和元器件自主可控程度,设计一种完全国产化的30MHz~512MHz超宽带功率放大器,采用传输线巴伦和微带混合电路实现大功率宽带匹配,同时利用反馈网络改善平坦度指标,使用电路仿真软件(ADS)优化匹配电路。实测数据表明,本文研制的功率放大器输出功率大于53dBm,同时漏极效率优于60%。In order to improve the domestic production rate of communication equipment,and meet the demands of our localization of military equipment.In this paper,a 30MHz~512MHz ultra wideband power amplifier was designed,which using transmission line balun and micro-strip hybrid circuit to realizing high-power wideband matching,and feedback network is used to improve the flatness index.Then ADS simulation software was used to simulate the circuit.The measured datas show that the output power of the PA is more than 53dBm,and the minimum efficiency of the PA is 60%,in the band of 30MHz~500MHz.
