Description
Technical field
The invention belongs to electronic communication technology fields, arrange cavity configuration more particularly to one kind for realizing communicating equipment product
Simplification the open cross coupling structure of 13-14.
Background technique
We often use 13-14 cross-coupled manner in communication product, especially in combiner, the products such as duplexer
The ratio of middle utilization is wide.13-14 cross-coupled manner is by between non-adjacent chamber plus capacitive or inductive coupled, and by pressing
The microwave signal for sequentially travelling coupling is compared, and this coupling across between non-adjacent chamber produces the phase of one+degree or-degree
It moves, is superimposed upon on the signal for coupling of advancing in order, one or two transmission zero is just produced outside the passband of communication product
Point, to substantially improve the Out-of-band rejection of communication product.It can simplify the design of zero point using 13-14 cross-coupling benefit,
In the design of conventional, it is difficult to arrange since the characteristic of 13-14 nesting zero point causes to be easy to appear isolated island in mechanical structure
Screw causes to be easy to produce signals leakiness influence electrical performance indexes and mechanical structure is difficult to realize.
Summary of the invention
Present invention aims at provide a kind of letter for realizing communicating equipment product row's cavity configuration in view of the drawbacks of the prior art
The open cross coupling structure of the 13-14 singly changed.
The present invention to achieve the above object, adopts the following technical scheme that
A kind of open cross coupling structure of 13-14, including cover board, the resonant column of cavity and setting in the cavity；It is described
Have on cover board and adjusts screw；The cavity and resonance column form four resonant cavities, are arranged between non-conterminous two resonant cavities
There are cross coupling elements, it is characterised in that: the first resonant cavity and the second resonant cavity, the second resonant cavity and third resonant cavity, third
It is the Open architecture without partition wall between resonant cavity and the 4th resonant cavity；Rank is provided between first resonant cavity and the 4th resonant cavity
Scalariform partition wall.
It is further characterized by: the cross coupling elements are arranged on the ladder-like partition wall.
A kind of form: the cross coupling elements are capacitive coupling element.
The capacitive coupling element is fixed on ladder-like by the supporting element and PEEK screw that are arranged on ladder-like partition wall
On partition wall.
The resonant column is rectangular or round.
The present invention is mainly characterized by: becoming full open model cross-coupling on original non-open type cross-coupled manner has
Effect solves combiner, duplexer etc. the problems such as mechanical structure difficulty is realized, avoids isolated island and signals leakiness, and realization is not changing
Client's index is met in the case where becoming cavity body structure.

Specific embodiment
Below with reference to specific example, the present invention is described in more detail.
As shown in Figure 1-3, a kind of open cross coupling structure of 13-14, including cover board 5, cavity 8 and setting are in cavity 8
Interior resonant column 1.Have on the cover board 5 and adjust screw 6, is connected by screw 7 and cavity 8.The cavity 8 and resonant column 1
Four resonant cavities are formed, are provided with capacitor copper sheet 2 between non-conterminous two resonant cavities.First resonant cavity and the second resonant cavity,
Second resonant cavity and third resonant cavity are the Open architecture without partition wall between third resonant cavity and the 4th resonant cavity；First is humorous
Ladder-like partition wall 9 is provided between vibration chamber and the 4th resonant cavity.
The capacitor copper sheet 2 is fixed on ladder-like by the supporting element 4 and PEEK screw 3 that are arranged on ladder-like partition wall 9
On partition wall 9.Resonant column 1 and the electrical property for adjusting the main realization combiner of screw 6: frequency and bandwidth.The combiner cross-coupling
Mechanical structure is easily realized.
In conclusion using technical solution of the present invention, having broken conventional structure mode, limited to cause product structure to occur lonely
The problems such as island and signals leakiness, realizes the simplification and limitation of product.
The above be that a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
Specific implementation of the invention is only limited to these instructions.For any people for being familiar with this technology and its field, this hair is not being departed from
Under the premise of bright design, various deductions or change may be made, the protection scope of the utility model all should belong to.
