Description
Technical Field
The utility model relates to a multiplexer public port technique among the wireless communication field especially relates to a multiplexer public port device.
Background
In a modern wireless communication system, a base station multiplexer module is composed of a plurality of filter channels, and since the plurality of filters need to be merged at an ANT port, at present, in the existing common port technology of the multiplexer, each filter channel is directly connected to the common port through a transmission line, or the common port is manufactured by using a common cavity. In some structural constraints, the ANT combiner ports cannot be directly coupled through a common cavity.
Chinese utility model patent publication No. CN201243077 discloses a multiplexer common port, including a set of connecting wire, a set of regulation minor matters, input/output port and earthing terminal, the connecting wire links to each other with each filter passageway to connect in input/output port and form the route, the connecting wire links to each other with ground through adjusting the minor matters. The utility model discloses a to influence mutually and be difficult to master and the multiplexer common port of preparation, replace with a set of interconnecting link that has the regulation minor matters, realize the multiplex through the regulation minor matters on the regulation connecting wire, this kind of structure greatly reduced the preparation degree of difficulty of common port, improved the efficiency of production. The problem that the ANT combiner port cannot be directly coupled through a common cavity is not solved.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is that current ANT closes way port and can't directly carry out the coupling through a public chamber, provides a multiplexer public port device for this reason.
The technical scheme of the utility model is that: a multiplexer common port device, comprising: a main rod transmission line; the ANT port is connected to one end of the main rod transmission line; the first combining port is connected to a port, close to the ANT, of the main rod transmission line; the first path filter is communicated with the first combining port; the second combining port is connected to the other end of the main rod transmission line; a common cavity communicating with a second combining port; and the second filter is communicated with the second combiner port through the common cavity.
In the above scheme, the first filter includes a first filter.
In the above scheme, the second filter includes a second filter, a third filter, a fourth filter and a fifth filter connected in parallel in the common cavity.
In the above scheme, the first filter includes a first filter and other filters.
The beneficial effects of the utility model are that the combination port can require to produce various changes according to concrete structure, the combination structure of arbitrary combination needs.

Detailed Description
The technical solution in the embodiment of the present invention is clearly and completely described below with reference to the accompanying drawings. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments of the ordinary skilled person in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the utility model comprises: a main rod transmission line 2; an ANT port 1, wherein the ANT port 1 is connected to one end of a main rod transmission line 2; the first combining port 3 is connected to a position, close to the ANT port 1, of the main rod transmission line 2; a first path filter communicated with the first combining port 3; a second combining port 4, where the second combining port 4 is connected to the other end of the main rod transmission line 2; a common cavity 6, the common cavity 6 being in communication with the second combining port 4; and the second path of filter is communicated with the second combining port 4 through the common cavity 6.
As an embodiment of the present invention, the first filter includes the first filter 5, and the second filter includes the second filter 7, the third filter 8, the fourth filter 9 and the fifth filter 10 connected in parallel in the common cavity 6. The first filter is directly connected to the main rod transmission line, and the second to fifth filters are combined through the common cavity and then connected to the main rod transmission line.
As another embodiment of the present invention, the first filter includes the first filter 5 and other filters, and the others herein refer to additional filters, such as the sixth filter, the seventh filter, etc., which are also connected in parallel to the first combining port through the common cavity. The second filter comprises a second filter 7, a third filter 8, a fourth filter 9 and a fifth filter 10 which are connected in parallel in the common cavity 6.
The utility model connects a plurality of filter channels in parallel through a transmission line main rod; the combination port can be varied according to the specific structure requirement, and in the example, the combination port belongs to a combination structure of 1+4, and similarly, the combination port has a form of 2+3/3+2, and the like.
