Description

Highly integrated multisystem mixing platform

Technical field

The utility model is related to a kind of communication passive device POI systems, more particularly, to a kind of highly integrated multisystem mixing Platform.

Background technology

POI（Point of interface, multisystem mixing platform）Mostly customed product, for different application rings Border, operating frequency combiner and electric bridge combiner, by the multiple business of access（CDMA, GSM, WCDMA, UMTS, LTE etc.）Letter Number combining, and the signal after combining is introduced into antenna feeder compartment system, reach the purpose for making full use of resource, reducing investment outlay.This is System is mainly used in the heavy construction in-door covering such as conference and exhibition center, exhibition center, airport, subway, and the system also there is input power to examine Survey and combining power output detection function, monitoring input, output port signal power size and the detection of output port standing wave etc. Function.

Traditional POI systems usually contain that system is more and index is complicated, for multiplefrequency mixer it is unnecessary it is no each Input port, is required to be hinged with 50 ohm of matched loads, when this input port is more, the quantity of matched load can not subtract It is few, cause system line complicated, cost increase, reliability decrease.

Utility model content

The purpose of this utility model is to overcome the defect of prior art there is provided a kind of absorbing load quantity is few, structure letter Single highly integrated multisystem mixing platform, by port combining, can effectively reduce connection, reduce cost.

To achieve the above object, the utility model proposes following technical scheme：A kind of highly integrated multisystem mixing platform, institute Stating combining platform includes the first combiner and the second combiner, and first combiner includes a plurality of first filter units, often Individual first filter unit is connected with the signalling channel of corresponding band, and second combiner includes a plurality of second filter units, The homonymy combining of second filter unit described at least two is provided with absorption negative into a combining port on the combining port Carry.

Preferably, first combiner and the second combiner are connected with power divider respectively.

Preferably, the power divider is three-dB coupler.

Preferably, all the second filter unit combinings into a combining port.

The highly integrated multisystem mixing platform of the utility model takes out multiple ports for needing to connect absorbing load by wave filter After head one road port of synthesis, absorbing load is reduced, or even only needs to connect one, simplifies connection.Because absorbing load quantity subtracts Few, the line between load and port is also reduced therewith, and system cost reliability is improved, cost reduction.

Brief description of the drawings

Fig. 1 is to use the utility model combining platform structure schematic diagram.

Reference：1st, the first combiner, the 11, first filter unit, the 2, second combiner, the 21, second filter unit, 3, Power divider, 4, load, 5, combining port.

Embodiment

Below in conjunction with accompanying drawing of the present utility model, the technical scheme progress to the utility model embodiment is clear, complete Description.

The highly integrated POI systems of the utility model mainly include the first combiner 1, the second combiner 2, the and of power divider 3 Load 4, the combiner 2 of the first combiner 1 and second is connected with power divider 3 respectively, and first combiner 1 includes multiple Several first filter units 11, each first filter unit, which is connected with the signalling channel of corresponding band, Fig. 1, shows four The embodiment of one filter unit, second combiner 2 includes showing the second conjunction in a plurality of second filter units 21, Fig. 1 Into a combining port 5, absorbing load is provided with the combining port 5 by three the second filter unit combinings for the homonymy of road device 4, the power divider 3 is connected with the antenna-feedback system port outside the utility model.

In this case, the first combiner 1 and the second combiner 2 can be set to, with product processed, set combining port When can substantially reduce design difficulty by the way that the taps of multiple second wave filters is synthesized into a road port, simultaneously because absorbing Load number is reduced, and the line between load and port is also reduced therewith, and system cost reliability is improved, cost reduction.

As shown in figure 1, in this specific embodiment, combining port 5 is by three the second filter unit combinings, another second filter Ripple unit is provided with GSM900 signalling channels, optionally, and combining port can also be two the second filter unit combinings, Either multiple second filter unit combinings, the unit of other non-combinings is separately provided load.

In the present embodiment, the power divider is three-dB coupler, and its side is by two ports respectively with described first Combiner 1, the second combiner 2 are connected, and its opposite side is connected by port with antenna-feedback system respectively, optionally, power point Orchestration can also be other passive devices such as electric bridge.

Compared with conventional method connects multiple absorbing loads, absorbing load quantity can be subtracted by the utility model structure It is few, or even only one absorbing load is reduced to by multiple, system cost reliability is improved, cost reduction, while decreasing line The complexity on road, alleviates POI overall weight, and volume is also reduced, and replaceability is good, and cost is substantially reduced.

Technology contents and technical characteristic of the present utility model are had revealed that as above, but those skilled in the art still may be used A variety of replacements and modification without departing substantially from the utility model spirit can be made based on teaching of the present utility model and announcement, therefore, this Utility model protection scope should be not limited to the content disclosed in embodiment, and should include various without departing substantially from replacement of the present utility model And modification, and covered by present patent application claim.
