Integrated polarization multiplex and duplex component

Abstract

The invention discloses an integrated polarization multiplex and duplex component which comprises an ortho-mode coupler and two duplexers, wherein the input ends of the two duplexers are respectively connected to a horizontal polarization output end and a perpendicular polarization output end of the ortho-mode coupler; the multiplex and duplex component is characterized in that through the perpendicular polarization output end, perpendicular polarization electromagnetic wave is converted to be in a horizontal polarization mode by virtue of a turning structure, so that a tuning screw of the duplexer at the perpendicular polarization end is located on the same plane with a tuning screw of the duplexer at the horizontal polarization end. The structure disclosed by the invention needs fewer devices, and is simple in structure, low in cost, high in integration degree, good in reliability and easier in processing; electric property indicators are more excellent.

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 / feed antenna with reflector mounted waveguide diplexer-OMT (patent number: US 20030184487 A1), in which the OMT uses a diaphragm structure OMT, The performance of the OMT in this structure is unreliable, and its duplexer is also non-tunable, which requires extremely high processing accuracy; the OMT of the Cross-Polar and Co-Polar Transceiver (Patent No.: US 20070296518 A1) in 2007 uses The structure of replacing the metal diaphragm with a metal rod is a big improvement compared with the previous one, but people need to install it manually later, which affects the performance. In addition, it is made of many parts spliced ​​together, and the tuning screws are not on the same plane, so the cost Very high, inconvenient to debug, not convenient 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 a metal diaphragm to isolate cross-polarized electromagnetic waves, but it is difficult to guarantee the processing accuracy and installation accuracy and reliability of the diaphragm, which causes 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
