Description
Technical field
The present invention relates to a kind of wave filter, and in particular to a kind of wave filter of quick adjustment filter effect.
Background technology
Microwave filter is an extremely important part in many modern microwaves, millimeter-wave systems, the quality of its performance
Often directly affect the performance of whole system.Due to the growing tension of radio-communication frequencies resource, various types of communication system
Working frequency will develop to the microwave of higher frequency even millimeter wave.In order to better profit from frequency spectrum resource, various communication frequencies
It is it is required that narrow.Now regulation generally use multiple-stage filtering to filter effect is carried out, so do can not effectively save resource, carry
The using effect of high single wave filter, at present there has been no a wave filter, can quickly adjust filter effect.
The content of the invention
The technical problems to be solved by the invention are that current wave filter quickly can not be adjusted to filter effect,
It is only capable of being filtered by the way of control signal source or multiple-stage filtering, it is an object of the invention to provide a kind of quick adjustment filter
The wave filter of ripple effect, solve the problems, such as above-mentioned.
The present invention is achieved through the following technical solutions：
A kind of wave filter of quick adjustment filter effect, including the left and right ends of waveguide are provided with export structure, described
Waveguide side is provided with several rectangular apertures, and the trend of the rectangular aperture is vertical with waveguide direction, the metallic plate
Insert in rectangular aperture, the waveguide region between two neighboring metallic plate forms resonator, is additionally provided with the waveguide
Adjusting screw, sector gear is provided with the rectangular aperture of the waveguide, the sector gear is engaged with metallic plate, regulation
Metallic plate inserts the depth of waveguide.It is engaged by sector gear with the rack on metallic plate, metallic plate can be allowed to carry out
Lower movement, the depth of regulation metallic plate insertion waveguide, raising or the aisle spare for reducing waveguide, so as to filtering
Effect carries out quick mechanical adjustment, can so reduce and be filtered adjustment using multiple wave filters so that in a filtering
It can just carry out adjusting filter effect in real time on pipeline.
Further, be provided with three rectangular apertures on the waveguide, the sector gear in the opening from left to right according to
Secondary equal proportion increase, scaling up 1:2:3.Three rectangular apertures set, and the sector gear in the opening is successively etc.
Ratio increase is to carry out different depth adjustments, and the bigger metallic plate coordinated with it of sector gear is just inserted into waveguide
It is deeper, allow whole wave filter to realize the effect of multiple-stage filtering.
Further, the mode of operation of at least 2 resonators is the higher mode of the resonator in the resonator.Here
Resonator can be any cross section column resonator, be preferred with cylindrical cavity and rectangular cavity.As more preferable
Selection, the high-order mode resonance chamber is rectangular cavity and its mode of operation is TE102 moulds.
In general, using soldering or the welding conducting of other methods between metallic plate and waveguide, to prevent microwave signal
It is outer or cause unnecessary coupling between adjacent resonators to be radiated the wave filter.In order to improve the Q values of resonator, filter is reduced
The Insertion Loss of ripple device, waveguide and the sheet metal surface can be silver-plated.Adjustment of the present invention because needing progress metallic plate, so
Using filling plastic film between waveguide and metallic plate, and the metal consistent with waveguide material is sprayed in film surface
Paint, reduces the influence to filtering.
Further, the metallic plate is towards being provided with rack on the end face of sector gear side.Using sector gear and
Rack coordinates, and is easy to allow sector gear to be arranged on waveguide, and can reduce space, influences the filter effect of wave filter, adopts
It with sector gear, can either ensure that metallic plate can be moved up and down, and can enough reduces gap, improves the filtering effect of wave filter
Fruit.
The present invention compared with prior art, has the following advantages and advantages：
1st, a kind of wave filter of quick adjustment filter effect of the present invention, change filtering can be moved up and down by metallic plate
Area, change filtering；
2nd, a kind of wave filter of quick adjustment filter effect of the present invention, the sector gear of multiple different proportions of setting, matches somebody with somebody
Multiple-stage filtering can be carried out simultaneously by closing metallic plate.
