Description
Technical field
The utility model belongs to feeder line technical field, is specifically related to a kind of binary channels coupler.
Background technology
MIMO technology is the Chief technology of TD-LTE, and this technology not only can improve channel capacity to anti-multipath fading, simultaneously can also elevator system total throughout and single user throughput.As the obvious indoor distribution scene of high-speed data service demand, the networking of its TD-LTE also will adopt based on twin-channel MIMO technology.In the middle of the process of actual networking, a lot of property point is built single channel compartment system (GSM/TD-SCDMA), be difficult to when another paths newly-built ensure that the path loss with former existing passage is completely the same, the problem of binary channels unbalanced power will be produced like this.The situation of binary channels unbalanced power, will produce certain impact to the downlink business performance of system, particularly when binary channels unbalanced power degree is more than 3dB, impact is obvious, and the region of impact mainly concentrates on twin-channel fringe region.Therefore, in the scene actual design of TD-LTE indoor distribution and in building, the generation avoiding the uneven situation of binary channels should be measured as possible.
At present, two-way room divide in coupler be all single installation, all joints need manual manufacture when mounted, and the technique of joint is uneven, cause power loss different.The device that installation two is identical is needed in the installation place of each coupler, although be two identical devices, be likely that different manufacturers produces, this province of device also exists difference, the device of namely identical quality also needs installation twice, labor intensive.
Summary of the invention
For overcoming above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of binary channels coupler, have structure simple, be easy to promote and feature easy to use.
For achieving the above object, the technical solution adopted in the utility model is: a kind of binary channels coupler, includes coupler A and coupler B, and the straight-through end of coupler A is connected with straight-through end of integrated binary channels coupler; The coupled end of coupler A is connected with integrated binary channels coupler input A; The input of coupler A is connected with integrated binary channels coupler input B; Integrated binary channels coupler input A is connected with the coupled end of coupler B; The input of coupler B is connected with integrated binary channels coupler input B; The straight-through end of coupler B is connected with straight-through end of integrated binary channels coupler.
Signal shielding layer is provided with between described coupler A and coupler B.
Described integrated binary channels coupler input A is connected with the coupled end of coupler B by integrated binary channels coupler interconnector;
The beneficial effects of the utility model are:
Compared with prior art, the utility model adopts twin-channel coupler, and current single pass coupler is carried out integration packaging, assembles in a box by two common couplers, middle interpolation signal shielding layer, the inner connection being carried out interface by the technique of standard; Adopt integrated coupler to need the work of making two joints to become original each joint and only make a joint, greatly reduce the power deviation that manufacture craft is brought.Have structure simple, be easy to promote and feature easy to use.
The utility model is adopted to reduce constructional difficulties significantly, decrease the quantities of construction, reduce the generation due to unbalanced power between the passage produced artificial in work progress, the equipment simultaneously avoiding different manufacturer is used with, or the problems such as the passive device of different model are employed at same position, construction two-way room is divided become with build at present single channel room divide the same convenient, flexibly, the development follow-up for LTE provides sound assurance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, structural principle of the present utility model and operation principle are described in further detail.
See Fig. 1, a kind of binary channels coupler, includes coupler A1 and coupler B2, and the straight-through end 3 of coupler A1 leads directly to end 12 with integrated binary channels coupler and is connected; The coupled end 4 of coupler A1 is connected with integrated binary channels coupler input A5; The input 6 of coupler A1 is connected with integrated binary channels coupler input B7; Integrated binary channels coupler input A5 is connected with the coupled end 9 of coupler B2; The input 10 of coupler B2 is connected with integrated binary channels coupler input B7; The straight-through end 11 of coupler B2 leads directly to end 12 with integrated binary channels coupler and is connected.
Signal shielding layer 13 is provided with between described coupler A1 and coupler B2.
Described integrated binary channels coupler input A5 is connected with the coupled end 9 of coupler B2 by integrated binary channels coupler interconnector 8;
Operation principle of the present utility model is:
Use two same models, with the coupler package of performance in a passive device, external interface is encapsulated into one, and the encapsulation adopting mechanized equipment to carry out joint makes, ensure that each joint is equal to the working portion loss of coupler, make the performance of two couplers the same.Made the two paths of signals pad value of binary channels coupler equal.
