Description
Technical field
The invention belongs to electronic communication technology field, particularly relate to a kind of novel low-cost wave guide ring being easy to processing
Device.
Background technology
Circulator is the device of a kind of three-port irreversible, has the characteristic of one-way transmission higher frequency signal energy.Annular
Device applies to communication base station system, radar system etc. widely.Main Function is as transceiver insulation, power in such systems
Amplifier and low-noise amplifier input and output isolation and decoupling etc., thus reach protection system and improve system stability and can
Purpose by property.The development globalized along with current mobile communication and the determination of 5G communication altofrequency frequency spectrum, circulator is special
It is that the waveguide junction circulator demand of high frequency can get more and more.Additionally more and more higher along with communication base station system integrated level, more
Occasion need directly the circulator of waveguide is integrated in the duplexer of waveguide front-ends.Can give birth on a large scale waveguide junction circulator
Requirement in terms of producing property, low cost, integration is more and more higher.
The most conventional waveguide duplexer designs as it is shown in figure 1, this structure is a symmetrical structure, at waveguide Y shape knot
Waveguide top and bottom respectively process the boss of a triangle, on upper lower convex platform, each ferrite installing one piece of triangle, whole
Structure is intermediate symmetry.Also being that the narrow limit subdivision from waveguide is opened during actual processing, whole circulator includes two
Magnet steel required for the cavity of individual symmetry, 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 this structure is integrated in waveguide duplexer, waveguide duplexer just will be made to become
It is two cavitys rather than conventionally used cavity and the structure of a cover plate, ripple will be increased thus greatly
Lead the cost of duplexer.
Summary of the invention
Present invention aim at for existing waveguide junction circulator cost high, the defect of processing difficulties, it is provided that a kind of structure letter
Single, easy to process novel low-cost waveguide junction circulator.
The present invention for achieving the above object, adopts the following technical scheme that
A kind of waveguide junction circulator, including y-shaped waveguide duplexer, it is characterised in that: arrange in the cavity of described y-shaped waveguide duplexer
Having two triangle boss stacked together, center is all tied with Y in the cavity of y-shaped waveguide duplexer in the center of two trianglees
Overlapping, the side length of lower triangular boss is more than the side length of upper triangular boss, the three of two triangle boss
Individual angle is respectively directed to three ports of described y-shaped waveguide duplexer；Described upper triangular central upper is provided with ferrite block, institute
State ferrite block and be provided above magnet steel.
Described ferrite block can be circular or triangle.
It is further characterized by described waveguide junction circulator and includes wave guide ring body and cover plate, described waveguide junction circulator
The internal cavity that is machined with, described cover plate and waveguide junction circulator mates form the cavity of y-shaped waveguide duplexer；Described ferrite
It is lined with PTFE between block and cover plate, described cover plate is provided with the magnet steel installing hole for mounting magnetic steel.
In order to simple installation consolidates, the thickness of two described triangle boss, ferrite block and PTFE stacking is relative to institute
Stating cavity height in waveguide junction circulator body is plus tolerance.
Waveguide junction circulator of the present invention uses unsymmetric structure, it is only necessary to a cavity, a cover plate, one piece of ferrite, and one
Block PTFE and one block of magnet steel.Therefore compared to the waveguide junction circulator of prior art, low cost, easily it is integrated in waveguide duplexer
In.
Accompanying drawing explanation
Fig. 1 is existing waveguide junction circulator structural representation.
Fig. 2 is inside cavity structural representation of the present invention.
Fig. 3 is that the present invention assembles structure three-dimensional schematic diagram.
Detailed description of the invention
A kind of waveguide junction circulator is the circulator of a waveguide Y knot form.If Fig. 2 is its inside cavity structure, have three
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 at the center of two triangle boss with waveguide Y, and wherein first
The area of triangle boss 1 is more than the area of the second triangle boss 2, due to the existence 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
It is provided with ferrite block 3, after described ferrite block 3 is by adding loaded magnetic field, it is possible to achieve the function of the unidirectional isolation of circulator；Described
Ferrite block 3 can be circular or triangle.Described ferrite block 3 top is provided with PTFE 4, and described 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, described cover plate 6 has the magnet steel installing hole 8 of mounting magnetic steel 7, described first triangle boss 1 and second
Triangle boss 2 is directly processed in the cavity in wave guide ring body 5.When waveguide junction circulator is installed, first pass through a work
Ferrite block 3 is arranged on the middle position of the second triangle boss 2 by clamps, secondly PTFE 4 is placed on ferrite block 3
Top, then with cover plate 6, ferrite block 3 and PTFE 4 is compacted on wave guide ring body, finally magnet steel 7 is arranged on lid
In magnet steel installing hole 8 on plate 6, whole assembling process is very simple, is well suited for producing on a large scale.Owing to PTFE 4 has one
Fixed elasticity, so at waveguide junction circulator when designing, specially carrying out interference design by the thickness direction size of PTFE 4, therefore
When pushing down ferrite block 3 and PTFE 4 with cover plate 4 during assembling, a pressure the biggest will be produced, can be by ferrite
It is the most firm that block 3 and PTFE 4 is pressed.This design can solve in conventional annular device, and ferrite must stick with glue the shortcoming connect,
Both saved cost, and can avoid again causing loss to increase because there being the pollution of glue, and under vibration working condition, have more
High reliability.
The above is to combine concrete preferred implementation further description made for the present invention, it is impossible to assert
Being embodied as of the present invention is confined to these explanations.For any people being familiar with this technology and field thereof, without departing from this
On the premise of bright design, various deduction or change may be made, all should belong to this novel protection domain.
