A ridge waveguide microstrip probe eight-way power combining/power dividing network

Abstract

The invention discloses a ridge waveguide microstrip probe eight-way power combining / power dividing network, comprising a planar microstrip probe printed board, a first box body, a second box body andan intermediate cover board. The planar microstrip probe printed board divides one signal power into two paths or synthesizes two signals into one signal. A first metal groove of the first box body,a second metal groove of the second box body and a metal through groove of the intermediate cover plate form an input / output port of a ridge waveguide cavity and a double ridge waveguide; A ridge waveguide cavity and an intermediate cover plate convert the double-ridge waveguide into two single-ridge waveguides, and two planar microstrip probe printed boards are respectively fixed at the ends of the two single-ridge waveguides; Four planar microstrip probe printed boards are provided with signal input / output ports, and signals are coupled to the planar microstrip probe printed boards through the microstrip probes. The eight-way power combining sub-network of the invention has small volume, wide coverage frequency band, simple form, small size and wide coverage frequency band of the planarmicrostrip probe printed board, and can be applied to various waveguide synthesis / power sub-network.

Description

technical field [0001] The invention belongs to the field of wireless communication, and in particular relates to a ridge waveguide microstrip probe eight-way power combining / dividing network. Background technique [0002] In modern mobile communication technology, high-power solid-state power amplifier is an important part. The output power of a single solid-state amplifier is limited, and in order to obtain greater output power, power combining is required. Combining / power dividing network is a basic power combining unit, and a series of indicators such as insertion loss, amplitude-phase consistency, and power capacity have an important impact on the performance of power combining. Due to the large loss of the traditional planar synthesis circuit, the synthesis efficiency is low, especially in the broadband multi-channel synthesis, the synthesis efficiency will be further reduced, and the power amplifier is bulky. [0003] At present, the quasi-space combining / power divi...

AI Technical Summary

Problems solved by technology

The existing quasi-spatial combination / power division network mainly includes coaxial and microstrip probes and rectangular waveguide and microstrip probes. The coaxial form is not conducive to the integration of waveguide systems, and the processing and assembly requirements are very high. The structural form of the shaft determines its poor heat dissipation performance, poor reliability and stability, and other disadvantages; while the rectangular waveguide has the disadvantages of narrow coverage frequency band, large volume and weight, and high production cost.
