Abstract
The utility model discloses a public port of a duplexer and a multiplexer. The public port comprises a coupling cancellation mechanism, an insulation supporting body and cavity walls, the insulation supporting body is fixed on the cavity wall between first cavities of different channels, and the coupling cancellation mechanism is supported between the first cavities of different channels via the insulation supporting body. Energy positive coupling generated by an open structure of cavity space can be offset so that the realizability of multiplexing and the effect of a multiplexing port of the multiplexer are improved.
Description
Technical field
The utility model relates to a kind of duplexer, the multiplexer common port in wireless communication field.
Background technology
In existing radio communication detecting system, the application of duplexer, multiplexer is very extensive, more anxiety along with radio spectrum resources, duplex and multiplex's frequency band is more and more nearer, the difficulty that duplexer implements is also increasing, and wherein the problem of the phase mutual interference of duplex mouth, multiplex's mouth also highlights.For duplexer or multiplexer, the size of disturbing between every two paths directly affects the overall performance of duplexer or multiplexer.Therefore, the interference how reduced between each path of multiplexer is one of technology intersection point of industry concern.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly can effectively reduces crosstalking between each path, thus the technical scheme that the multiplex (MUX) of common port is achieved.
For above-mentioned purpose, a kind of duplexer of the utility model, multiplexer common port adopt following technical scheme:
A kind of duplexer, multiplexer common port, comprise coupling disappear mutually mechanism, insulation support body and chamber wall, described insulation support body is fixed on the chamber wall between adjacent the first chamber of different paths, and the described coupling mechanism that disappears mutually is supported between adjacent the first chamber of different paths by insulation support body.Described the first chamber is the resonant cavity of close feed in each passage channel.Described multiplexer is the coaxial cavity multiplexer.
As the further optimization of such scheme, described coupling disappears mechanism mutually for negative coupling adjuster.Negative coupling adjuster is connected the signal between two adjacent the first chambeies of path, by change negative coupling adjuster the inside cavity volume the number regulate the size of negative coupling amount.
As the further optimization of such scheme, described negative coupling adjuster is 1.
As the further optimization of such scheme, described negative coupling adjuster is cylindrical shape metallic conductor or rectangular-shaped metallic conductor.
As the further optimization of such scheme, described coupling disappears mechanism mutually through insulation support body, and disappear the mutually two ends of mechanism of coupling are suspended in the air in adjacent the first chamber of different paths.
The beneficial effects of the utility model main manifestations is: a multiplexer, be by feed by the signal coupling of different frequency to each passage, and the just coupling that has produced a kind of energy by structural space opening between each passage first chamber, thereby this coupling can make between each passage to produce to disturb and destroy multiplex's effect, and the utility model be by an insulation support body by a metallic conductor frame between interactional chamber, thereby introduced a kind of negative coupling, the energy that this negative coupling can be offset because of the open generation of space structure just is coupled, thereby multiplex (MUX) phase multiplex's realizability and the effect of multiplexer multiplex (MUX) mouth have been improved.
The accompanying drawing explanation
Fig. 1 is the duplexer cavity body structure schematic diagram in the utility model.
Fig. 2 is the duplexer common port structure for amplifying schematic diagram in the utility model.
Fig. 3 is the duplexer common port structural representation that adds negative coupling adjuster in the utility model.
Fig. 4 is the four multiplexer common port structural representations that add negative coupling adjuster in the utility model.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model will be further described.
As shown in Figures 2 and 3, a kind of duplexer, multiplexer common port, comprise coupling disappear mutually mechanism, insulation support body 2 and chamber wall 3, described insulation support body 2 is fixed on the chamber wall 3 between adjacent the first chamber of different paths, described coupling disappears mechanism mutually through insulation support body 2, and disappear the mutually two ends of mechanism of coupling are suspended in the air in adjacent the first chamber of different paths.Described coupling disappears mechanism mutually for 1, negative coupling adjuster, and described negative coupling adjuster 1 is the cylindrical shape metallic conductor, and described the first chamber is the resonant cavity of close feed in each passage channel.The insulating material that described insulation support body 2 is arbitrary shape.
Just be coupled and referring between adjacent the first chamber of each path the Energy Coupling that the opening due to structure space produces, negative coupling refers to the Energy Coupling contrary with this positive coupling polarity.
Thereby change the size of negative coupling amount by changing the volume of negative coupling adjuster 1 in cavity, make it offset the just coupling between adjacent first chamber of different paths of bringing due to structure space, and then improve the realizability of multiplex's mouth.
The above is explained in detail the utility model preferred implementation by reference to the accompanying drawings, but the utility model is not limited to above-mentioned execution mode, in the ken possessed those of ordinary skills, can also under the prerequisite that does not break away from the utility model aim, make a variety of changes.
Do not break away from design of the present utility model and scope and can make many other changes and remodeling.Should be appreciated that the utility model is not limited to specific execution mode, scope of the present utility model is defined by the following claims.
