摘　　要：针对现有合成方式的不足,提出了一种新型结构四路波导分支耦合器,具有驻波好、隔离度高和结构紧凑等优点。介绍了波导—微带探针过渡结构和波导T型结的原理及设计方法,对无源网络进行了建模仿真,通过优化达到了功放设计所需的性能指标。对有源电路的装配工艺进行了简要介绍。基于4个16 W功放模块和四路功率分配/合成网络,设计了一种50 W毫米波固态功率放大器,在所需频段实现了大于50 W的输出功率,整机效率高于18%。In order to solve the deficiency of the current binary power combination,a novel four-way branch-waveguide coupler ispresented,which features low VSWR,high isolation and compact construction. The principle and design method of waveguide-microstrip transition and T-junction waveguide is introduced. And the simulation models of passive network are founded, which achieved the required performance through optimizing. The assembling technology of active circuit is introduced briefly. A 50 W millimeter-wave solid power amplifier is developed, based on four 16 W power amplifier modules and four-way power divider / combiner. The output power of power amplifier is more than 50 W in desired frequency band,and the efficiency is more than 18%.
