Prismatic Multiplex Power Distribution/Combiner Based on Sector Branch Microstrip Line

Abstract

The invention provides a prismatic multi-path power distributor / synthesizer based on a fan-shaped branch microstrip line. The prismatic multi-path power distributor / synthesizer based on the fan-shaped branch microstrip line is wholly prismatic and comprises a power distribution section and a power synthesis section, wherein the power distribution section and the power synthesis section are of the same structure, electromagnetic waves enter a cavity through an input end coaxial connector, and synthesized high-power signals are output from the cavity through an output end coaxial connector. An impedance deploy hole is punctured in a microstrip planar circuit of a fan-shaped branch power distribution / synthesis structure, the isolation among branches can be improved, the whole structure is connected through microstrip patches, and therefore the power distribution / synthesis structure can achieve a wide work frequency band. According to the requirement of actual power synthesis, by reasonably designing the size and position of the impedance deploy hole and the radius of the fan shape, equal-power distribution of all the branches can be achieved, and different power distribution / synthesis path numbers can be achieved conveniently according to the needs.

Description

technical field [0001] The invention relates to the microwave field, in particular to a multi-channel power distribution / combiner. Background technique [0002] As an important part of microwave and millimeter wave radar, guidance, communication, and testing systems, microwave and millimeter wave solid-state power amplifiers have become an important research direction in the field of microwave and millimeter waves. In microwave and millimeter wave solid-state power amplifiers, due to the limitation of the power amplifier chip by its own semiconductor physical characteristics, as well as the influence of heat dissipation, manufacturing process and impedance matching, single-chip amplifiers often fail to meet the requirements of high-power signals in actual engineering. Therefore, in order to meet the high-power requirements of communication and test systems, it is necessary to use a method of combining power with multiple amplifier branches. Commonly used power distribution / ...
