An integrated polarization multiplexing duplex component

Abstract

The invention discloses an integrated polarization multiplexing duplex assembly, which includes an orthogonal mode coupler and two duplexers, and the input ends of the two duplexers are respectively connected to the level of the orthogonal mode coupler. The polarization output end is connected with the vertical polarization output end, and it is characterized in that: the vertical polarization output end changes the vertically polarized electromagnetic wave into a horizontal polarization mode through a steering structure, so that the vertical polarization end duplexer The tuning screws of the horizontal polarization duplexer and the tuning screws of the duplexer are on the same plane. The invention has few structural devices, simple structure, low cost, high integration, good reliability, easier processing, and better electrical performance index.

Description

technical field [0001] The invention belongs to the technical field of electronic communication, and in particular relates to an integrated polarization multiplexing duplex component for realizing polarization multiplexing 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. At present, major communication equipment manufacturers (including Ericsson, NEC, Huawei, ZTE, etc.) are carrying out related research and development work. [0003] In order to achieve polar...

Problems solved by technology

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

People have done a lot of work before, such as the 2003 US patent Reflector / feedantenna with reflector mounted waveguide diplexer-OMT (patent number: US 20030184487A1), in this patent, what OMT uses is the OMT of diaphragm structure, in this The performance of the structural OMT is unreliable, and its duplexer is also non-tunable, which requires extremely high processing accuracy; in 2007, the OMT of Cross-Polar and Co-PolarTransceiver (Patent No.: US 20070296518 A1) uses a metal rod The structure that replaces the metal diaphragm, although it has been greatly improved compared with the previous one, still needs to be manually installed later, which affects performance. In addition, it is made of many parts spliced ​​together, and the tuning screws are not on the same plane, so the cost is very high. Debugging Inconvenient and inconvenient for large-scale production

The products proposed in these two patents have complex structures and difficult processing, and only realize the integrated function, which proves the technical feasibility of this integration from theory and practice, but the product forms they propose cannot achieve scale. production, applied in actual engineering

This is due to the following two reasons (1) Traditional OMT requires metal diaphragms to isolate cross-polarized electromagnetic waves, but the processing accuracy and installation accuracy and reliability of the diaphragms 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 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 together, due to 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 more parts in the entire device, which not only increases the production cost, but also leads to performance degradation. The tuning screws are not on the same surface, which will cause great trouble during production debugging
