The utility model discloses can realize the screening to the microwave signal to reach the useless or even harmful signal of filtering, guarantee the effect of desired signal transmission, owing to adopt new face structural style, more do benefit to the integration, the batch production of being convenient for, and adopt guide wavelength design in eight minutes small, light in weight, the reliability is high.
Description
Technical field
This utility model relates to a kind of miniaturization waveguide filter.
Background technology
Waveguide filter, owing to adopting high q-factor structural design, this wave filter has the ability of high power work, there is relatively low Insertion Loss, good passband stationary wave characteristic and higher attenuation outside a channel, temperature stability is good, is particularly suitable for arrowband application, is widely used in the fields such as radar, electronic countermeasure series of products, microwave communication, radio frequency simulation.Normal response adopts 0.1dB Chebyshev response.Different index requests according to user are also frequently with Butterworth, elliptic function, Bezier and linear phase shift response design.Several tuned cells are to provide the waveguide segment of the frequency characteristic needed.
Conventional waveguide duplexer in the market is all half waveguide wavelength design, and the too big unfavorable installation of volume is integrated.
Utility model content
The purpose of this utility model is in that to overcome the deficiencies in the prior art, it is provided that a kind of miniaturization waveguide filter, adopts eight point of one waveguide wavelength design, overcomes conventional waveguide duplexer volume big, the problem being unfavorable for transferring the shortcoming of integrated use to.
The purpose of this utility model is achieved through the following technical solutions: a kind of miniaturization waveguide filter, it includes wave-guide cavity wave, cover plate and tuning screw, described cover plate is sealed and welded in the bottom of wave-guide cavity wave, multiple tuning screws arrange the top with wave-guide cavity wave, one end of wave-guide cavity wave connects first wave guide mouth, the other end of wave-guide cavity wave connects second waveguide mouth, and the wavelength of described wave-guide cavity wave is 1/8th waveguide wavelengths.
Described cover plate be red copper cover plate or silver-plated after Aluminum cover.
Described wave-guide cavity wave adopts slotting cutter to empty the mode machine-shaping of metal.
The beneficial effects of the utility model are: this utility model is parts crucial in communication system, in the electronic equipments such as setting and microwave communication, satellite communication, radar equipment, Aero-Space, for channel filtering clutter, to realize required microwave signal normal transmission and to suppress the device with outer noise signal relevant.
The screening to microwave signal can be realized, thus reaching to filter useless even unwanted signals, it is ensured that the effect of useful signal transmission.Owing to adopting the version of novelty, it is more conducive to integrated, it is simple to batch production；And adopting eight point of one waveguide wavelength design volume little, lightweight, reliability is high.

Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, a kind of miniaturization waveguide filter, it includes wave-guide cavity wave 1, cover plate 2 and tuning screw 3, described cover plate 2 is sealed and welded in the bottom of wave-guide cavity wave 1, multiple tuning screws 3 arrange the top with wave-guide cavity wave 1, one end of wave-guide cavity wave 1 connects first wave guide mouth 4, and the other end of wave-guide cavity wave 1 connects second waveguide mouth 5.Wherein, wave-guide cavity wave 1 does not adopt half traditional waveguide wavelength design, and adopts eight point of one waveguide wavelength design, reduces the volume of whole waveguide filter, is beneficial to installation.
Specifically, microwave signal inputs from first wave guide mouth 4, by wave-guide cavity wave 1, and connects output from second waveguide mouth 5, reaches required microwave signal normal transmission and suppress to be with outer noise signal.
Wave-guide cavity wave 1 uses CNC milling machine or Cutter Body Processing with Machining Center molding in block of metal, takes to empty the mode working groove of metal with slotting cutter；Cover plate 2 be red copper cover plate or silver-plated after Aluminum cover be sealed and welded on wave-guide cavity wave 1；And debugged by special screw 3 of coordinating.
