Technical field
This utility model belongs to electronic communication technology field, more particularly to a kind of novel low-cost waveguide for being easy to process
Circulator.
Background technology
Circulator is a kind of device of three-port irreversible, the characteristic with one-way transmission higher frequency signal energy.Annular
Device widely applies to communication base station system, radar system etc..Main Function is as transceiver insulation, power in such systems
Amplifier and low-noise amplifier input and output isolation and decouple etc., system stability and can is improved so as to reach protection system
By the purpose of property.The development globalized with current mobile communication and the determination of 5G communication altofrequency frequency spectrums, circulator are special
The waveguide junction circulator demand for being high frequency can be more and more.In addition with communication base station system integrated level more and more higher, more
Occasion need directly the circulator of waveguide is integrated in the duplexer of waveguide front-ends.Can give birth on a large scale to waveguide junction circulator
Producing property, the requirement in terms of low cost, integration also more and more higher.
At present conventional waveguide duplexer design as shown in figure 1, the structure is a symmetrical structure, at waveguide Y shape knot
Each one triangle of processing in waveguide top and bottom boss, the ferrite of one piece of triangle is respectively installed, entirely on upper lower convex platform
Structure is in intermediate symmetry.It is also to open from the narrow side subdivision of waveguide during actual processing, whole circulator includes two
Magnet steel required for individual symmetrical cavity, two pieces of ferrites and two pieces of gyromagnets.Thus cost is of a relatively high.And tend not to be readily integrated into
In waveguide duplexer, because if the circulator of the structure is integrated in waveguide duplexer, waveguide duplexer will be just caused to become
For two cavitys, rather than the structure of a conventionally used cavity and a cover plate, thus will greatly increase ripple
Lead the cost of duplexer.
The content of the invention
This utility model purpose is for existing waveguide junction circulator high cost, the defect of processing difficulties, there is provided Yi Zhongjie
Simple, the easy to process novel low-cost waveguide junction circulator of structure.
This utility model for achieving the above object, is adopted the following technical scheme that：
A kind of waveguide junction circulator, including y-shaped waveguide duplexer, it is characterised in that：In the cavity of the y-shaped waveguide duplexer
Two triangle boss stacked together are provided with, the center of two trianglees is all tied with Y in the cavity of y-shaped waveguide duplexer
Center superposition, the side length of lower triangular boss are more than the side length of upper triangular boss, two triangle boss
Three angles be respectively directed to three ports of the y-shaped waveguide duplexer；The upper triangular central upper is provided with ferrite
Block, is provided with magnet steel above the ferrite block.
The ferrite block can be circular or triangle.
Which is further characterized by：The waveguide junction circulator includes wave guide ring body and cover plate, the waveguide junction circulator
The cavity of cavity, the cover plate and waveguide junction circulator mates formation y-shaped waveguide duplexer is machined with vivo；The ferrite
PTFE is lined between block and cover plate, the magnet steel installing hole for mounting magnetic steel on the cover plate, is provided with.
In order to simple installation is firm, the thickness of two triangle boss, ferrite block and PTFE stackings is relative to institute
It is plus tolerance to state cavity height in waveguide junction circulator body.
This utility model waveguide junction circulator adopts unsymmetric structure, it is only necessary to a cavity, a cover plate, one block of ferrum oxygen
Body, one block of PTFE and one block of magnet steel.Therefore compared to the waveguide junction circulator of prior art, low cost is easily integrated in waveguide
In duplexer.

Fig. 2 is this utility model inside cavity structural representation.
Fig. 3 is this utility model assembling structure schematic three dimensional views.
Specific embodiment
A kind of waveguide junction circulator is the circulator that a waveguide Y ties form.If Fig. 2 is its inside cavity structure, three are had
Individual port.There is in cavity the first triangle boss 1, the second triangle boss 2；First triangle boss 1 and the third angle shape
Boss 2 is all processed on wave-guide cavity wave bottom surface, and center superposition is all tied with waveguide Y in the center of two triangle boss, wherein first
Area of the area of triangle boss 1 more than the second triangle boss 2, due to the presence of the two triangle boss, whole ring
Shape device frequency response curve meets second order Chebyshev's response curve, has wider bandwidth of operation.Second triangle boss top
Ferrite block 3 is provided with, the ferrite block 3 is after loading magnetic field, it is possible to achieve the function of circulator one-way isolation；It is described
Ferrite block 3 can be circular or triangle.3 top of the ferrite block is provided with PTFE 4, and the PTFE 4 is except thickness
Outward, other sizes are all identical with ferrite block.
Fig. 3 is the installation diagram of waveguide junction circulator, including wave guide ring body 5, ferrite block 3, PTFE 4, cover plate 6,
The magnet steel 7 of permanent magnet, the magnet steel installing hole 8 with mounting magnetic steel 7, first triangle boss 1 and second on the cover plate 6
Triangle boss 2 is directly processed in the cavity in wave guide ring body 5.When installing waveguide junction circulator, first by a work
Ferrite block 3 is arranged on clamps the middle position of the second triangle boss 2, and PTFE 4 is placed on ferrite block 3 secondly
Top, then ferrite block 3 and PTFE 4 are compacted on wave guide ring body with cover plate 6, finally by magnet steel 7 be arranged on lid
In magnet steel installing hole 8 on plate 6, whole assembling process is very simple, is well suited for large-scale production.As PTFE 4 has one
Fixed elasticity, so when waveguide junction circulator is in design, the thickness direction size of PTFE 4 is carried out into interference design specially, therefore
When ferrite block 3 and PTFE 4 are pushed down with cover plate 4 in assembling process, will produce a very big pressure, can be by ferrite
It is very firm that block 3 and PTFE 4 are pressed.The design can be solved in conventional annular device, ferrite must with the gluing shortcoming for connecing,
Both cost had been saved, can have been avoided again causing loss to increase because there is the pollution of glue, and under vibration working condition, be had more
High reliability.
The above is with reference to specific preferred implementation further detailed description of the utility model, it is impossible to
Identification is of the present utility model to be embodied as being confined to these explanations.For any people for being familiar with this technology and its field, not
On the premise of departing from this utility model design, various deductions or change may be made, should all belong to this new protection domain.
