Abstract
The utility model relates to an integrated MIMO coupler. The integrated MIMO coupler is characterized by comprising a shell which comprises an upper plate for abutting against a wall and side plates connected with two sides of the upper plate. The two side plates are provided with two or more sets of slot hole channels for fixing passive device connectors at corresponding positions. The integrated MIMO coupler simplifies troubles of fixing a plurality of passive devices in the same area during construction of MIMO indoor distribution signal coverage, by directly merging the two or more sets of conventional couplers and power dividers into a whole on the integrated passive device. Due to integration of the passive devices, most of terminals can realize parallel, thereby facilitating assembly and stay wire of front and back transmission cables. Besides, materials are saved and cost can be reduced.
Description
technical field:
The utility model relates to integrated MIMO coupler.
background technology:
In recent years, along with the sharp increase of communication apparatus to information technology demand, communication apparatus proposes higher requirement to the transmission rate of wireless communication system and transmission performance.But due to the scarcity of radio spectrum resources, wireless communication system will reach higher transmission rate and better transmission performance, just needs wireless communication system must have higher spectrum efficiency.MIMO(Multiple Input Multiple Output, multiple-input, multiple-output) technology is one of key technology of LTE, utilize multi-antenna technology (transmitting or receive diversity, spatial reuse and wave beam forming), be that multichannel transceiver path is worked simultaneously, on limited frequency spectrum resource, can realize two-forty and large capacity, improve greatly user's experience.
Indoor distributed system current 2, that NodeB is used is all only supported unipath, and frequency range is generally 800M-2.5G frequency range, cannot transmit simultaneously indoor base station 2,3G multipath radiofrequency signal, thereby cannot bring into play the technical advantage of 4G LTE.Its solution just only has LTE path of new laying.
The in the situation that of 2 road signal path, 2 road paths on same routing path, usually need to lay respectively two bars transmission lines, 2 couplers, 2 power splitters etc.In this case, two devices that simultaneously use, are overlapping in position, but separate, need to be fixed respectively installation, have increased the difficulty of carrying out project installation on limited construction space.
utility model content:
The purpose of this utility model is to provide a kind of integrated MIMO coupler, and this integrated MIMO coupler is conducive to directly merge conventional indoor distribution passive device, to reduce spatial volume, simplifies construction.

Above-mentioned biside plate dual-side is provided with cover plate, and described lid surface is provided with several screw holes, and described cover plate is fixed by being arranged in screw in screw hole and the framework on shell body.
Above-mentioned each side plate dual-side is respectively provided with a slotted eye road, and this slotted eye road is the dark breach that is located at side plate dual-side.
On above-mentioned side plate, near slotted eye road bottom land, be provided with four screw holes, in order to fixing of two passive device joints, in cover plate side edge surface, be provided with two screw holes, for side plate in four screw holes two screw holes form four fixedly screw holes of passive device joint.
Above-mentioned upper plate is provided with fixedly uses slotted eye.
Above-mentioned shell body is square.
A coupler is installed in above-mentioned every group of slotted eye road.
A power splitter is installed in above-mentioned every group of slotted eye road.
?the integrated MIMO coupler of the utility model by will existing two groups or more coupler and power splitter directly merges as a whole on this integrated passive device, thereby make to simplify the trouble of fixing a plurality of passive devices at the same area when the covering of MIMO indoor distribution signal is constructed.Integrated due to passive device, port is many can realize parallel, convenient before and after transmission cable assembling and bracing wire.Also save material, reduced cost.
