摘　　要：利用波导电桥和微带双探针设计了一种Ku波段80 W固态功率放大器。波导电桥用于提高合成通道间的隔离度,波导-微带双探针则可提高模块集成度,从而实现了高密度集成下的大功率输出。该功率放大器在13.5～14.5 GHz频率范围内可实现80 W脉冲功率输出,且合成效率高于81％,附加效率高于25％。This paper describes a Ku-band 80W solid-state power amplifier by using the waveguide bridge and waveguide-to-microstripe double probes transform structure. The waveguide bridge is used to improve the rejection rate between combination channels, and the waveguide-to-microstripe double probes transform structure can increases the integration of modules. Accordingly a higher power output is realized owing to the high dense integration. The pulse output power of this amplifier is 80W at 13.5 - 14. 5 GHz with the corresponding power combining efficiency better than 81%.and the power added efficiency greater than 25%.
