The utility model relates to a cross-coupling coaxial structure for penetrating non-coupled cavity, belonging to a technical field of microwave communication, which solves the problem that cross-coupling structure between the prior straight cavity 1, the straight cavity 2 and the straight cavity 3 is difficult to be realized. The utility model adopts a coaxial cable, the bare internal conductors 6 at two ends of the coaxial cable are extended into the straight cavity 1 and the straight cavity 3 of the coupled cavity, a middle coaxial cable 5 is arranged fixedly at two walls of the straight cavity 2 by a clamping seat 4, the connection method of the bare internal conductors 6 are adjusted according to the length and coupling requirement of the coaxial cable so as to realize capacitive coupling or perceptual coupling. The cross-coupling coaxial structure for penetrating non-coupled cavity has the advantages of simple structure, low cost, and being easy to realize cross coupling of linear arrangement of coupled cavity. The utility model is suitable for microwave coaxial cavity filter.

Description

A kind of cross-couplings coaxial configuration that passes through non-coupling cavity
Technical field
This patent relates to a kind of cross-couplings coaxial configuration that passes through non-coupling cavity, belongs to technical field of micro communication.
Background technology
All be staggered between traditional coaxial cavity filter cavity, carry out perception or capacitive coupling by flying bar between the cavity, in the reality often since the requirement in space must carry out straight chamber and arrange, adopt so traditional solo flight bar between straight chamber be can't realize cross-linked.
Summary of the invention
At the above-mentioned defective of prior art, this patent will solve the problem that straight chamber cross-couplings is difficult to realize.
For solving the problems of the prior art, this patent relates to a kind of cross-couplings coaxial configuration that passes through non-coupling cavity, for solving existing straight chamber (1), straight chamber (2), need cross-couplings between the straight chamber (3) and problem that structure is difficult to realize, select a coaxial wire for use, the exposed inner wire (6) at coaxial wire two ends stretches in straight chamber of coupling cavity (1) and the straight chamber (3), middle coaxial cable (5) is fixed on by deck (4) on two walls of cavity (2), and the connected mode of regulating exposed inner wire (6) according to the length and the coupling requirement of coaxial cable realizes capacitive coupling or inductive coupled.
In this patent, described coaxial wire can be connected on the cavity bottom, also can be connected on the sidewall of cavity.
In this patent, described coaxial wire can replace with optical copper wire, and the characteristic impedance of optical copper wire and chamber wall equals the coaxial wire characteristic impedance.
The beneficial effect of this patent is that coupling coaxial cable line structure has been realized cross-couplings between the straight chamber, has increased transmission zero, has improved the outer suppression characteristic of band.
Description of drawings
Below in conjunction with drawings and Examples this patent is described further, in the accompanying drawing:
Fig. 1 is a kind of cross-couplings coaxial configuration that passes through non-coupling cavity of this patent.
Among Fig. 1,1,2,3 is three straight chambeies, and 4 is deck, and 5 is middle coaxial cable, and 6 are exposed inner wire.
Embodiment
In the preferred embodiment of this patent, in three straight chambeies 1,2,3 of duplexer, selecting one section characteristic impedance for use is that 50 Ω, length are the coaxial wire of 85mm, the exposed inner wire 6 at coaxial wire two ends stretches in straight chamber 1 of coupling cavity and the straight chamber 3, middle complete coaxial cable 5 is fixed on two walls in straight chamber 2 by deck 4, according to calculating λ/4=c/4 v=3*108/4 (800*106)=93.75mm, coaxial cable length is less than quarter-wave, with exposed inner wire 6 two ends of coaxial cable unsettled realization capacitive cross-couplings.
To describe a kind of characteristics of passing through the cross-couplings coaxial configuration of non-coupling cavity of present embodiment below in detail.
1, described coaxial wire two ends exposed copper conductor, centre are exposed.
2, described coaxial wire adjustable length.
3, described coaxial wire exposed copper inner wire is connected on the sidewall.
4, described coaxial wire does not adopt optical copper wire.
Behind a kind of cross-couplings coaxial configuration that passes through non-coupling cavity that adopts this patent, realize cross-couplings between the straight chamber, increased transmission zero, improved the outer suppression characteristic of band.
