In this paper, a series of compact power combiners are designed based on multimode transmission lines. Based on the multimode transmission lines, several multiport mode networks are constructed to achieve two-way, three-way, and four-way high-isolation power combinations. In detail, a four-port mode network based on a rectangular coaxial dual-mode transmission line and a five-port mode network based on a rectangular three-ridge three-mode transmission line are designed to achieve compact high-isolation two-way power combination. A six-port mode network based on a circular-coaxial three-mode transmission line is designed to achieve compact high-isolation three-way power combination. A nine-port mode network based on a four-ridge dual-coaxial six-mode transmission line is designed to achieve compact high-isolation four-way power combination. Based on a compact multimode transmission line, two-way, three-way, and four-way power combinations can be realized with single stages, high isolation, compact cross section sizes, low insertion loss, and high power capacity. The corresponding methods can be used to design several excellent power combiners.
本文基于多模传输线设计了一系列紧凑型功率合成器。基于多模传输线，构建了多个多端口模式网络，以实现双向、三向和四向高隔离功率合成。具体而言，设计了基于矩形同轴双模传输线的四端口模式网络和基于矩形三脊三模传输线的五端口模式网络，以实现紧凑型高隔离双向功率合成。设计了基于圆形同轴三模传输线的六端口模式网络，以实现紧凑型高隔离三向功率合成。设计了基于四脊双同轴六模传输线的九端口模式网络，以实现紧凑型高隔离四向功率合成。基于紧凑型多模传输线，可通过单级实现双向、三向和四向功率合成，具有高隔离度、紧凑的横截面尺寸、低插入损耗和高功率容量。相应方法可用于设计多种优异的功率合成器。
