【摘要】 本文提出了基于短路枝节加载的带通滤波型功率分配器的设计方法。通过设计一个滤波型阻抗变换器,并将其合成一个三端口功率分配器。隔离性能通过在两个阻抗变换器中跨接多个隔离电阻进行实现。基于此设计方法,提出了三种三类拓扑结构,分别是标准型、优化型,以及带外抑制增强型。每一种类型均提供了设计实例、EM仿真与加工实测结果,最终验证了理论的正确性。基于本文中提出的方法,所设计的三种功率分配器的带宽分别为107.3%、66%和53%,隔离度分别为-19.8 dB、-18.5 dB和-26.2 dB。更多还原

【Abstract】 Based on short-circuited stubs,this paper presents a design approach for a band-pass filtering power divider.By designing two filtering-type impedance transformer,a three-port power divider can be easily synthesized.Isolation performance will be achieved by connecting multiple isolation resistors which bridge these two impedance transformers.Then,three types of topologies are proposed from the above design apprach,which are standard type,optimized type,and out-of-band suppression enhanced type.Finally,design examples,EM simulation and measured results of these three types are verified for the design theory.Based on the proposed method,the bandwidths of three designed power dividers are 107.3 %,66 % and 53 %,and the isolation of S32 are-19.8 dB,-18.5 dB and-26.2 dB,respectively.更多还原
