Integrated waveguide radio frequency front-end component

Abstract

The invention discloses an integrated waveguide radio frequency front-end component. The component comprises an ortho-mode coupler, a waveguide directional coupler and three duplexers, and is characterized in that one of a horizontal polarization output end and a vertical polarization output end of the ortho-mode coupler is connected with the waveguide directional coupler, wherein two output ends of the directional coupler are connected with one duplexer respectively; the other output end of the ortho-mode coupler is connected with the other duplexer; after the vertical polarization output end or the horizontal polarization output end of the ortho-mode coupler is steered through a steering mechanism, the three duplexers are on the same plane. The component has the advantages of few structural devices, simple structure, low cost, high integration, high reliability, high easiness in machining and more superior electrical performance index.

Description

technical field [0001] The invention belongs to the technical field of electronic communication, and in particular relates to an integrated waveguide radio frequency front-end component, which is used to realize polarization multiplexing and real-time backup of communication equipment. Background technique [0002] People have higher and higher requirements on the communication rate and the reliability of communication equipment. The most effective way to solve the communication rate is to increase the number of channels. However, in today's increasingly crowded electromagnetic spectrum, it is obviously unrealistic to simply increase the bandwidth, so the polarization complex Using it becomes the most effective way to increase the channel, and the communication rate can be doubled through cross-polarization multiplexing. The most direct way to improve equipment reliability is to implement system backup. At present, major communication equipment manufacturers are developing ...

Problems solved by technology

[0006] However, it has always been a difficult problem to integrate these three devices together with better manufacturability and meet the needs of mass production.

People have done a lot of work before, such as Blen Albert Louis, Desargant Glenn J. in 2003; Evangelos Avramis, Peter Hopkinson, David John Roulston, Ronald P.A. Schiltmans, etc. in 2007 have integrated OMT and duplexer as a whole, but The reported products all have complex structures and processing difficulties, and cannot achieve large-scale production

However, the integration of the three devices has not been reported

This is due to the following two reasons (1) Traditional OMT requires a metal diaphragm to isolate cross-polarized electromagnetic waves, but the processing accuracy of the diaphragm and the accuracy and reliability of the installation are difficult to guarantee, which results in the traditional OMT manufacturing process There must be certain substandard products in

If the traditional OMT is used to integrate the directional coupling and the duplexer, once the OMT is unqualified, the entire integrated device will be scrapped, resulting in a large economic loss; (2) The traditional method used to integrate the OMT and the duplexer At the same time, because the polarizations of the two electromagnetic wave signals are perpendicular to each other, the output port of the duplexer and the tuning screw must not be on the same plane, which leads to many parts of the entire device, which not only increases the production cost, but also leads to The performance is degraded, and the tuning screws are not on the same surface, which will cause extremely troublesome production debugging
