Abstract

The invention discloses a magic tee power divider based on a novel matching structure. The magic tee power divider mainly comprises a first output rectangular waveguide, an input rectangular waveguide and a second output waveguide, wherein the input rectangular waveguide and the second output waveguide are connected with the first output rectangular waveguide. The matching structure is arranged in the first output rectangular waveguide, consists of at least two rectangular steps and a metal column and partially extends into the second output rectangular waveguide. The magic tee power divider based on the novel matching structure has the advantages that the magic tee power divider is simple in processing, the matching structure and a magic tee can be processed by milling once, assembly errors in matching result assembly are reduced, the phase position and amplitude balance at an output port are fine, and isolation ports are well isolated.

Description

technical field [0001] The invention relates to a power splitter, in particular to a magic T power splitter based on a novel matching structure. Background technique [0002] Power dividers and combiners are important components in microwave systems, which are used to distribute transmission power to different loads, or combine different power into one circuit to obtain greater power. The performance of the microwave power divider, such as insertion loss, isolation, phase balance and amplitude balance, will have an important impact on the performance of the entire system. At present, the common power divider is a distributed parameter power divider using microstrip line or cavity waveguide. The cavity waveguide power divider has small insertion loss and good amplitude balance, but its disadvantages are poor isolation and complicated manufacturing process. Contents of the invention [0003] The purpose of the present invention is to provide a magic T power divider with si...
