摘要
本文介绍一种新型的宽带大功率合成器/分配器。在这种功率合成器中用同轴线Balun阻抗变换器和假负载代替传统的W ilk inson功率合成器中隔离电阻;使得其工作带宽是传统的功率合成器的三倍左右。本文回顾了展宽W ilk inson功率合成器工作带宽的方法,然后分析这种新型的的功率合成器的特性,最后给出仿真结果并与传统功率合成器、双节级联功率合成器的仿真结果作比较。
A novel Broadband high - power combiner / divider with compensation circuit is presented in this paper. The isolating resistor between two dividing ports in conventional Wilkinson power combiner is replaced by a structure of coax balun transformer. With this coaxial structure, the bandwidth of this novel combner is three times wider than a conventional one. Some methods for increasing bandwidth are reviewed. Characteristic of this new combiner is analysed. Simulation results of the Conventional Wilkinson combiner, a bisection combiner and the novel combiner are given and compared in this paper.
