Abstract
The utility model relates to a multi-system combination platform cable separating apparatus comprising an uplink and a downlink which are both provided with combiners, wherein an uplink signal port is connected with the combiner which is connected with an antenna port via an electric bridge, the downlink signal port is connected with the combiner and is connected with a coupler via an electric bridge, and the output end of the coupler is connected with the input end of the antenna port. The multi-system combination platform cable separating apparatus resolves the technical problem of providing a low-loss high-separation high-intermodulation multi-system apparatus with point of interconnection (POI) technology, Point Of Interconnection, thus the design is simplified, the cost and construction difficulty are reduced, with further coverage, low word-losing rate and the like.
Description
Technical field
The utility model relates to a kind of communication and divides cable equipment, is specifically related to the branch cable equipment that a kind of multi-line closes the road system.
Background technology
POI is applied in the heavy construction urban operating mechanism that needs the multiple-network system access, as places such as subway railway station airport government of large-scale museum office passes.This POI equipment has realized that the many signals of multiband close the road function, wards off and has exempted from the overlapping investment that indoor distributed system is built, and is the effective means of the compatible covering of the many network signals of a kind of realization.As connecting a distant place and compartment system and bridge, the main effect of POI is the downstream signal of systems such as CDMAGSM DCS PHS WLAN 3G and cluster is closed the road, simultaneously the upward signal to each system is carried out shunt, and suppress the useless interference component between each frequency band as far as possible.Each the system's duplex signaling that comes from the telepoint base station antenna respectively inserts POI by a port, and port of equipment antenna feeder side picks out.Downstream signal carries out signal through power amplifier on multichannel unification road and covers, and the upward signal of user terminal then is by former passage reverse transfer, is that one road signal branch multichannel is got back to the uplink and downlink communication that separately system finishes system respectively.The cable device components was more in existing minute, and the high isolation of loss is low, complex structure, and manufacturing cost is higher.
The utility model content
The technical problem to be solved in the present invention provides that a kind of low-loss is high isolates high intermodulation POI multi-system equipment, and simplified design has reduced cost and difficulty of construction and covered fartherly, and it is low etc. to lose the words rate.
For addressing the above problem, the objective of the invention is to be achieved through the following technical solutions:
A kind of cable-distributing equipment for multisystem route-joining platform includes uplink and downlink, and uplink and downlink are equipped with mixer, and described upward signal port is connected with mixer, and mixer is connected with antenna port by electric bridge; The downstream signal port is connected with mixer, and mixer connects coupler by electric bridge, and the output of coupler is connected with the antenna port input.
A kind of cable-distributing equipment for multisystem route-joining platform, described up mixer are one four frequency combiner and one five frequency combiner.
A kind of cable-distributing equipment for multisystem route-joining platform, described descending mixer are two six frequency combiners.
A kind of cable-distributing equipment for multisystem route-joining platform, a side of described coupler is provided with detection port.
The present invention has following beneficial effect fruit;
1, performance index have significantly been optimized.Adopt the utility model, the insertion loss of POI is little, and passband fluctuation is little, and return loss is little, is with outer isolation height.
2, significantly reduced structural volume.Because used integrated and five six combinations that substituted double frequency and tri-frequency combiner frequently frequently, young pathbreaker's electric bridge is put into antenna and closes the road again simultaneously, has also reduced cost greatly with regard to significantly having reduced number of devices and volume like this.
3, be convenient to product in application in engineering.Owing to reduced product quantity and bulking value, improved product integrated level and modularization, be convenient to engineering staff's construction, especially can be reduced in the difficulty and the time of During Construction of Energy Room greatly, the size of also having dwindled machine room has reduced the cost of machine room.

Fig. 2 is the descending structural representation of the utility model.
Embodiment
Shown in accompanying drawing 1,2.
The utility model includes uplink and downlink, and uplink and downlink are equipped with mixer, and the upward signal port one is connected with mixer, and mixer is connected with antenna port 5 by electric bridge 4; The downstream signal port one is connected with mixer, and mixer connects coupler 7 by electric bridge 4, and the output of coupler 7 is connected with antenna port 5 inputs.Up mixer is one four frequency combiner 2 and one five frequency combiner 3.Descending mixer is two six frequency combiners 6.One side of coupler 7 is provided with detection port 8.During use, in up, the output signal that communication signal enters four frequency combiners 2 and five frequency combiners, 3, four frequency combiners 2 and five frequency combiners 3 enters a plurality of antenna ports 5 respectively by an electric bridge 4.In descending, the output signal that communication signal enters 6, two six frequency combiners 6 of two six frequency combiners enters a plurality of couplers 7 by an electric bridge 4, and a plurality of couplers 7 transfer signals to connected a plurality of antenna port 5 again.
