摘　　要：功率合成是获得高功率的一个重要技术途径,可以在单级高功率放大器的基础上将有效功率提高数倍。T型波导功率合成器作为一种空间功率合成器件,非常适合用于毫米波频段。但是怎样建立初始的波导功率合成器模型,如何利用电磁仿真软件进行优化,从而设计出一个具有良好性能的功率合成器,是一个复杂的问题。针对该问题,设计了一个改进型的波导功率合成器,结合电磁理论提出了一种新的优化设计方案,并得到了一种性能优良的波导功率合成器。The power combining technology is one of the important methods to get high power.It can enhance efficient power many times over that based on the single stage high power amplifier.As a kind of spatial power combiner,the T-junction waveguide power combiner is very suitable for millimeter-wave.How to get a model of the waveguide power combiner and how to use the electromagnetic field simulator to optimize it to design a good waveguide power combiner is a complicated problem.In order to solve the problem,this paper introduces an improved waveguide power combiner and a new optimization analysis according to the electromagnetic theory.And in the end,a T-junction waveguide power combiner with good performance is designed.
