Four-way single-/dual-band operation integrated filtering power divider (FPD) with new design topology is presented in this study. For either single- or dual-passband response, it involves only one same-type pair of multi-mode resonators and three isolation resistors, comparing with other existing four-way FPDs. By adopting the even-/odd-mode analysis method to flexibly control the resonant modes of the designed resonator and select isolation resistances, both single- and dual-band four-way filtering power division responses are specified and derived with the same one configuration. The proposed four-way FPD designs stand out from the reported ones by both nice operation performance, flexible topology with reduced number of resonators, and no additional feeding network at input port. For demonstration, two prototypes for four-way single- and dual-band FPDs are implemented following the given design procedure, respectively. Both simulated and measured results are exhibited to verify the theoretical design concept.

新型可调多模拓扑上紧凑型四路单频和双频滤波功率分配器的分析和设计

本研究提出了具有新设计拓扑的四路单/双频运算集成滤波功率分配器(FPD)。对于单通带或双通带响应,与其他现有的四向FPD相比,它仅涉及一对相同类型的多模式谐振器和三个隔离电阻。通过采用偶数/奇数模式分析方法来灵活地控制设计谐振器的谐振模式并选择隔离电阻,可以使用相同的一种配置来指定和推导单频带和双频带四路滤波功率分配响应。拟议的四向FPD设计在良好的操作性能,灵活的拓扑结构和减少的谐振器数量以及在输入端口没有额外的馈电网络方面均脱颖而出。为了示范 按照给定的设计步骤分别实现了四路单频和双频FPD的两个原型。展示了模拟结果和测量结果,以验证理论设计概念。
