Description
Technical field
The invention belongs to electronic communication technology field, more particularly to a kind of integrated polarization multiplexing duplex component, is used for
Realize the polarization multiplexing of communication equipment.
Background technology
People solve that traffic rate is maximally effective to be done to the reliability requirement more and more higher of traffic rate and communication equipment
Method is increase channel quantity, but in electromagnetic spectrum increasingly crowded today, it is obviously unrealistic simply by increase bandwidth, in
It is that polarization multiplexing is become to increase channel most efficient method, is multiplexed by cross polarization, traffic rate can be caused to increase by one
Times.At present major communications equipment manufacturer (including Ericsson, NEC, Huawei, in it is emerging etc.) all carrying out the development work of related fields
Make.
In order to realize polarization multiplexing in a communications device, the orthogonal mode couplings of OMT must be just used in waveguide radio frequency front end
Device and duplexer.
Way general at present is to separately design out OMT, duplexer.Then they are fitted together.Such benefit
It is that two kinds of devices separately design, difficulty is small, and technology maturation, risk is small, and the most device supplier of both waveguide devices is
It can provide.But its shortcoming is also fairly obvious：1. two kinds of combination of devices are together, due to that theoretic can not possibly match completely,
Performance indications decline is inevitably resulted in, echo is deteriorated, Insertion Loss increase, so as to influence the matching of transceiver unit and antenna, increase
System noise, reduce total emission power；2. two kinds of combination of devices are together, integrated level is not high, and volume is big, and weight is big；3. two kinds
Device purchases assembling respectively, and cost is high, and compatibility is low；4. gap inevitably be present at joint face in assembling in device, this
A little gaps can bring electromagnetic leakage, so as to bring electromagnetic compatibility problem；Waterproof and airtight problem, increase sealing can be also brought in addition
Cost；5. the increase of device count inevitably results in the complexity increase of system, global reliability reduces, so as to cause the later stage to set
Standby maintenance cost increase.
In order to overcome above mentioned problem, OMT and duplexer both devices are integrated into an entirety, one as system
Part is an effective selection.
But integrate both devices, and have preferable manufacturability, meet the needs of large-scale production,
An always problem.People be many work, such as the United States Patent (USP) Reflector/feed of 2003 before
The antenna with reflector mounted waveguide diplexer-OMT (patent No.s：US 20030184487
A1), in that patent, OMT is using the OMT of diaphragm structure, and OMT performances of structure are unreliable in this, in addition its duplex
Device be also it is non-tunable, it is high to requirement on machining accuracy；Cross-Polar and Co-Polar in 2007
Transceiver (the patent No.s：The A1 of US 20070296518) OMT using the structure that metallic membrane is replaced with metallic rod,
Although having larger improvement than before but stilling need later stage installation by hand, performance is influenceed, it is spelled using many parts in addition
Connect and form, tuning screw is not also in approximately the same plane, thus cost is very high, and debugging is also inconvenient, is not easy to large-scale life
Production.All there are complicated, processing difficulties in the product proposed in the two patents, be only to realize integrated function, from reason
By and practice on demonstrate this integrated technical feasibility, but the product form that they are proposed can not all realize scale
Production, among actual engineering.This is due to that the traditional OMT of following two reasons (1) needs metallic membrane isolation to hand over
Pitch polarization electromagnetic wave, but the precision of the processing of diaphragm and the precision of installation and reliability it is difficult to ensure that, this results in tradition
Necessarily there is certain defective work during OMT processing and manufacturings.If integrating duplexer with traditional OMT, just occur once OMT
It is unqualified, it may result in whole integrated device and all scrap, bring larger economic loss；(2) conventional method is by OMT and double before
Work device integrates, due to the mutually perpendicular reason of two-way electromagnetic wave signal polarization, the output port and tuning spiral shell of duplexer
Nail necessarily can not on the same face, and the part that this results in whole device is more, and so not only production cost is high, and can cause
Hydraulic performance decline, tuning screw on the same face, can not cause extremely onerous in scheduling and planning.
The content of the invention
The defects of present invention aims at for prior art, provides a kind of compact-sized, processing and easy to adjust, precision
Height, it is suitable for the integrated polarization multiplexing duplex component of large-scale mass production.
The present invention to achieve the above object, adopts the following technical scheme that：
A kind of integrated polarization multiplexing duplex component, including orthomode coupler and two duplexers, described two duplexs
The input of device is connected with the horizontal polarization output end and vertical polarization output end of the orthomode coupler respectively, its feature
It is：After the vertical polarization output end or horizontal polarization output end are turned to by a steering structure so that vertical polarization end
Duplexer and horizontal polarization end duplexer are in approximately the same plane.
A kind of embodiment：The vertical polarization output end is just become the electromagnetic wave of vertical polarization by a steering structure
For horizontal polarization mode so that the tuning screw of vertical polarization end duplexer and the tuning screw of horizontal polarization end duplexer are same
On one face.
It is further characterized by：The steering structure is rectangular waveguide, and the rectangular waveguide long side is parallel to orthogonal mode
Coupler vertical polarization output end, the rectangular waveguide short side is perpendicular to orthomode coupler vertical polarization output end.
The orthomode coupler realizes polarization separation by the way of slot-coupled.
Further：The resonator of described two duplexers is separately positioned on one piece of integral mold plate both sides, i.e. two duplexs
Device is made up of two parts of cavity and cover plate.Orthomode coupler part (nose heads), institute are connected with the middle part of the integral mold plate
Stating has wave-guide cavity wave on orthomode coupler part；The orthomode coupler part is orthogonal with the combined formation of integral mold plate
Mode coupler.
Using the waveguide 90 degree turning structure phase in an E face between the orthomode coupler and the duplexer of horizontal polarization
Even, the orthomode coupler is connected with the duplexer of vertical polarization using the waveguide 90 degree turning structure in a H face.
The new orthomode coupler OMT used in the present invention, using non-diaphragm polarization separation mode, overcomes biography completely
Because the problem of diaphragm causes to process difficulty in system orthomode coupler OMT.
In vertical polarization directions using a kind of brand-new patterns of change coupled modes, original orthogonal mode coupling is overcome completely
The problem of output port of duplexer and tuning screw can not be on the same face when device OMT and duplexer combine, so as to from
Truly realize integrated waveguide front end.
The present invention only has three part compositions in structure, is nose heads respectively, cover plate, cavity, has small volume, weight
Gently, simple in construction, cost is low, suitable for large-scale production.On electrical property, due to integrated design, device connection is avoided
During loss problem, thus substantially improve the Insertion Loss of whole front end, be computed than two kinds of integrated waveguide front end device and distinguish
Design, the front end of reconnection, Insertion Loss improve more than 0.4dB, and this will greatly improve the receiving sensitivity and transmitting work(of communication system
Rate, so as to improve the operating distance of system；The echo that mismachining tolerance is brought can be compensated by the tunning effect of duplexer in addition
Deteriorate, it is contemplated that using the waveguide front-ends of Integrated design compared to way before, can improve more than echo 5dB, receipts can be improved
Matching problem between hair machine and antenna, and the required precision of processing can be reduced, greatly reduce process time, reduce processing
