Description
Technical field
The utility model relates to technology for radio frequency fields, relate in particular to a kind of cross-coupled filter.
Background technique
With the continuous upgrading that grid frequency domain divides, the also constantly upgrading therewith of the parameter of filter, Out-of-band rejection frequency
Section increases therewith, degree of suppression also increases accordingly.Manufacturing enterprise is caused to be directed to the filter mold with old parameter designing whole
It scraps, causes the waste of a large amount of production cost.In addition, existing integrator has stringent customization requirement to equipment shape, lead
It causes row's chamber design of filter internal to be likely to encounter bottleneck, cross coupling capacitor can not be added on the basis of existing row's chamber.Therefore,
How a kind of novel cross-coupled filter is produced, it can be for new design parameter in existing filter row cavity configuration
Upper addition cross coupling capacitor solves the upgrade problem of old Project Product, increases the utilization rate in product design space, increases and produces
The flexibility of product design scheme.It is the direction that those skilled in the art need to study.
Utility model content
The utility model provides a kind of cross-coupled filter, can be for new design parameter on existing row's chamber basis
Upper addition cross coupling capacitor, realizes the upgrading of old Project Product, effectively increases the utilization rate and flexibility in product design space.
The specific technical solution that it is used is as follows:
A kind of cross-coupled filter, including outer housing are equipped at least three resonant cavities and at least one in the outer housing
Cross coupling capacitor group is organized, is respectively equipped with resonant rod in the resonant cavity；The cross coupling capacitor group includes cross-coupling electricity
Appearance and mounting medium；The mounting medium is fixed in outer housing, and the middle section of the cross coupling capacitor is installed on mounting medium
Upper, both ends are respectively protruding into two adjacent resonant cavities.
By using this technical solution: the existing low filter construction for inhibiting requirement being transformed, passes through to increase and hand over
The outer inhibition point of mode elevator belt for pitching coupled capacitor, effectively improves Out-of-band rejection index.
Preferably, in above-mentioned cross-coupled filter: being equipped with mounting base in the outer housing, the mounting base is set to two
Between a adjacent resonant cavity；The mounting base is equipped with the first mounting groove for installing mounting medium.
It is another Preferable scheme is that, in above-mentioned cross-coupled filter: the resonant rod is equipped with the second mounting groove, institute
The second mounting groove is stated for installing mounting medium.
It may further be preferable that in above-mentioned cross-coupled filter: the mounting medium uses polytetrafluoroethylene (PTFE).
Compared with prior art, the application can add cross-coupling on the basis of existing row's chamber for new design parameter
Capacitor realizes the upgrading of old Project Product, effectively increases the utilization rate and flexibility in product design space.
Detailed description of the invention
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:
Fig. 1 is the structural schematic diagram of the utility model embodiment 1；
Fig. 2 is the explosive decomposition schematic diagram of Fig. 1；
Fig. 3 is the structural schematic diagram of comparative example 1；
Fig. 4 is the simulation curve figure obtained using comparative example 1；

Each appended drawing reference and component names corresponding relationship are as follows:
1, outer housing；2, resonant cavity；3, resonant rod；4, cross coupling capacitor；5, mounting medium；6, mounting base；8, second
Mounting groove.
Specific embodiment
In order to illustrate more clearly of the technical solution of the utility model, further retouched below in conjunction with each embodiment
It states.
As shown in Figs. 1-2 it is the utility model embodiment 1:
It is humorous to be equipped with five arranged along a straight line in the outer housing 1 for a kind of cross-coupled filter, including outer housing 1
Vibration chamber 2 and one group of cross coupling capacitor group.Wherein, a resonant rod 3 is respectively equipped in each resonant cavity 2.The cross coupling capacitor
Group includes cross coupling capacitor 4 and mounting medium 5.
The second mounting groove 8 is equipped on the resonant rod 3 for being located at outer housing central location, 5 inlay card of mounting medium is the
In two mounting grooves 8.The middle section of the cross coupling capacitor 4 is installed on mounting medium 5, both ends be respectively protruding into it is two adjacent humorous
In vibration chamber 3.
It is illustrated in figure 3 comparative example 1, five resonant rods are all identical structure in comparative example 1, and there is no cross-coupling electricity
Appearance group structure.The Out-of-band rejection spectrogram of the two is as shown in attached drawing 4-5.Compare attached drawing 4,5, it is possible to find embodiment 1 is relative to comparison
Example 1 realizes Out-of-band rejection well.
The above, only specific embodiment of the utility model, but the protection scope of the utility model is not limited to
This, any those skilled in the art is in technical scope disclosed by the utility model, the variation that can readily occur in
Or replacement, it should be covered within the scope of the utility model.The protection scope of the utility model is with claims
Subject to protection scope.
