Technical field
The utility model is related to a kind of cavity body filter, more specifically, it relates to a kind of interdigitated S waves of 2GHz to 4GHz
Section cavity body filter.
Background technology
It is higher and higher to filter size requirement in many radio circuits, this requires that developing small-sized words, high-performance
Microwave filter.In general, the bandpass filter of S-band has the advantages of Insertion Loss is small, and Q values are high, but outer all using cavity form
Shape size is big, is not easy to be directly integrated in transceiver module.Microstrip line interdigital filter is although small, but Insertion Loss is big, degree of suppression
It is low, it is poor to the target signal filter of other frequency points or frequency range.,
Interdigital filter is a kind of microwave device for being detached to signal, can meet wave filter relative bandwidth
The technology requirement of wider wave filter, and conventional cavity body filter can not meet technology requirement of the relative bandwidth more than 25%.
In transceiver module, the main function of interdigital filter (abbreviation wave filter) be the signal that external antenna or radar receive into
Row filtering allows the signal that transceiver module needs by transceiver module, and the signal of other frequency points or frequency range is inhibited, and is allowed to
Being suppressed to does not influence the level of transceiver module normal work.
Utility model content

Wave band cavity body filter.
To achieve the above object, the utility model adopts the following technical solution：A kind of interdigitated S-band chambers of 2GHz to 4GHz
Fluid filter is fixed including cavity, cover board, tap resonant rod, fixed block, resonant rod, trip bolt A, trip bolt B, installation
Hole and radio frequency connector offer cavity fabrication hole and tap resonant rod installing technological hole, the tap resonance in the cavity
Bar is fixed with fixed block and passes through the installation of tap resonant rod installing technological hole in the cavity, and the resonant rod passes through trip bolt A
In the cavity, the radio frequency connector transit chamber body technology hole depth enters to be installed to inside cavity and is welded on tap resonant rod for installation
At installing technological hole, the cover board is arranged on cavity and passes through trip bolt B and locked.
As preference, the bottom of the cavity is equipped with installation mounting hole, cooperation is additionally provided at the installation mounting hole
Trip bolt C.
As preference, the cover board is consistent with cavity size and completely closely sealed.
As preference, the fixed block is fixed by socket on tap resonant rod.
The utility model is compared has the following advantages compared with the prior art：1st, it is processed using CNC equipment, machining accuracy
± 0.01mm is can reach, compared with traditional milling machine process equipment, raising machining accuracy that can be very big；2nd, it is humorous in resonator
Shake bar and cavity is by way of fixing screws, it is made to realize integration, the stability higher of product into an entirety；3、
It is welded between tap resonant rod and radio frequency connector, realizes coupled end and prolong without timing, realize that wave filter exempts to debug, supporting block
Tap resonant rod is reinforced, increases the stability of product；4th, cavity bottom facilitates and the product is consolidated there are 4 trip bolt holes
Determine into transceiver module.
Description of the drawings
Fig. 1 is the structure diagram of the interdigitated S-band cavity body filter embodiments of the utility model 2GHz to 4GHz.
In figure：Cavity (1), cover board (2), tap resonant rod (3), fixed block (4), resonant rod (5), trip bolt A (6),
