功率合成电路在固态发射机中得到了广泛应用。该文给出了一种宽频带多路功率合成器的结构，采用微带形式进行径向功率合成电路设计，具有宽带、合成路数灵活、结构实现简单的优点。合成器通过3节四分之一波长阻抗变换器构成的微带电路实现宽带匹配，以5路宽带功率合成器为例进行了仿真优化和设计以及实物验证，合成器在工作频段13GHz内插损小于0．5dB，测试结果与仿真结果吻合，表明了这种设计方法的可行性。

Power combining circuits are widely used in solid state transmitters .The structure of multi-way power combiner over a wide bandwidth is introduced in this paper .The combiner has the advantages of broad-band frequency , simple structure and arbitrary combining ports .The impedance match method by using multi-section microstrip is discussed .A particular design of combiner over a wideband 1 3GHz is presented and simulated.The combiner has an insertion loss of less than 0.5dB.Good agreement between simulated and measured results is found .This proves the validity of the design .
