摘要
为了获得带宽更宽、隔离度更好的功率分配/合成器,通过对Gysel功分器拓扑结构的改进,提出一种新型的功率分配/合成器;给出它的拓扑结构和设计参数,用奇偶模分析法分析了其工作原理,并借助微波CAD软件对该结构和Gysel功分器进行了对比分析。结果表明,该功率分配/合成器比传统的Gysel功分器具有更宽的带宽、更高的隔离度、以及更小的回波损耗。最后,设计并制作了C波段四路功分器并进行验证,测试结果表明其性能指标符合预期要求。
In order to design a power divider/combiner with wider band and superior isolation,a novel power divider/combiner based on the improvement of traditional Gysel power divider/ combiner is introduced. The topological structure and design parameters of this novel power divider/combiner have been presented and the operating principle has been analyzed by the odd- even model analysis. Simultaneously, detail comparisons between the two struotures have been performed using microwave CAD. The results show that the novel divider/combiner has wider band, better isolation and lower insert loss than Gysel power divider. A C - and power divider/combiner has been designed and the test results show that experiment and expectation are in good agreement.
