Description
Technical field
The present invention relates to electronic information and mobile communication equipment, be specifically related to a kind of mobile communication multisystem mixing platform machine.
Background technology
Along with being on the increase of mobile subscriber, the traffic density and the network coverage require constantly to rise; And the skyscraper in city also constantly increases, and these tall and big buildings have very strong shielding action to mobile telephone signal, cause a little less than the signal, and mobile phone can't normally use, and has formed the blind area of mobile communication.
Indoor covering system produces in this situation, and it is to utilize the domestic aerial compartment system that the signal of mobile base station is evenly distributed on indoor every nook and cranny, thereby has guaranteed the indoor desirable signal that has.Yet China's mobile communications network has: cdma network, GSM network, DTV digital TV network, DCS network, PHS network, WCDMA network, TD-SCDMA network, CDMA200 network, wlan network, WiMAX network or the like.In the time will covering multiple network in the same building, generally need to install respectively reception and emitter separately, this not only is provided with installs trouble, has also improved equipment cost simultaneously.Based on this problem, thus a kind of communication signal of multiple frequency can be merged and unified the transmission can be simplified communication apparatus and installed, reduce the multisystem mixing platform machine of communication apparatus cost and be born at this point.
Traditional multisystem mixing platform machine is with devices such as multiplefrequency mixer, electric bridge, filters, is in series by cable, forms an energy many nets signal is closed the road, or a signal is shunted to the platform device of a plurality of signals, it is concentrated in the cabinet again; But because device is more, cable connects more assorted, causes volume bigger, cost of idleness, and reliability is relatively poor etc.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, designed and developed out a kind of simple in structurely, volume is little, and the lower multisystem mixing platform machine of production cost.
The present invention is achieved by the following technical solutions:
A kind of multisystem mixing platform machine, comprise a cavity, the front end of this cavity is provided with a mixer signal output port, the rear end of cavity is provided with a plurality of system signal input ports, inside cavity is according to the corresponding some inner chambers of how much being divided into of signal input port, be arranged in order the resonance post in each inner chamber, wherein the input of two or more signal links to each other by a branch common cavity, a main common cavity is linked to each other with separately branch common cavity, each port of common cavity passed through capacitive coupling in common cavity in described minute again.
A kind of multisystem mixing platform machine, described capacitive coupling is for to be provided with the resonance post between two each ports of branch common cavity in main common cavity.
A kind of multisystem mixing platform machine, the resonance post in the described main common cavity passes through the boss bridge joint with resonance post in the described minute common cavity.
The present invention is by being provided with the resonance post between two each ports of branch common cavity in main common cavity.Can utilize the resonance post capacitive coupling at interior resonance post of main common cavity and branch common cavity inner port place.Can each resonance post be connected by lead like this, save the multiple layout of cavity inside conductor.Make simple in structurely, and maintenance and debugging is also more convenient.This structure setting has simultaneously also reduced the volume of multisystem mixing platform machine.

Embodiment
Elaborate the present invention below with reference to accompanying drawing.
By Fig. 1 and Fig. 2 as can be seen, the invention provides seven He Lu of system, it is provided with respectively and closes road signal output port 1, CDMA800 input port 2, the GSM of UNICOM input port 5, mobile GSM input port 6, CDMA2000 input port 4, TD-SCDMA (A) input port 8, TD-SCDMA (B) input port 7 and WCDMA input port 3.
See figures.1.and.2, cavity divides positive and negative to form by CDMA800 inner chamber (23,24), GSM inner chamber (561,564), CDMA2000 inner chamber (42,43), TDA inner chamber (82), TDB inner chamber (72), WCDMA inner chamber (33,34) and built-in electric bridge inner chamber (568).Each inner chamber is provided with CDMA800 resonance post (21,22), GSM resonance post (562,563), CDMA2000 resonance post (41,44), TDA resonance post (81), TDB resonance post (71), WCDMA resonance post (31,32) respectively, reserves inner chamber (YL) and built-in electric bridge inner wire (567).Every resonant cavity is arranged in order on request, opens coupling window (W) between the resonance post that links to each other.
Wherein CDMA800 is divided into two frequency range 825-835MHz and 870-880MHz, is connected to port 2 by wire jumper (25); GSM is divided into two frequency range 885-915MHz and 930-960MHz, is connected to the in-built electrical bridge joint mouth (566) at the back side by wire jumper (565), is divided into GSM of UNICOM (5) and mobile GSM (6) by same frequency combiner (electric bridge) again; CDMA2000 is divided into two frequency range 2110-2125MHz and 1920-1935MHz, is connected to port (4) by wire jumper (45); WCDMA is divided into two frequency range 2130-2145MHz and 1940-1955MHz, is connected to port (3) by wire jumper (35); TDA and TDB are connected to port (8,7) by wire jumper (83,73) respectively.
A among Fig. 1 is the resonance post of positive main common cavity, and it is A1, A2 and three frequency ranges of A3 by capacitive coupling, because frequency range needs, A2 capacitive coupling once more is A21 and two frequency ranges of A22.B among Fig. 2 is the resonance post of reverse side master common cavity, by capacitive coupling is B1, B2 and three frequency ranges of B3, because frequency range needs, B1 capacitive coupling once more is B11 and two frequency ranges of B12, B2 is owing to need, capacitive coupling is B21 and two frequency ranges of B22 once more, and B21 once more capacitive coupling be B211 and two frequency ranges of B212.More than describe as seen, can how much carry out repeatedly capacitive coupling according to frequency range, the alignment electrical property has not a particle of influence, produces convenience very and simple.The signal that capacitive coupling is closed behind the road is connected to joint (1) by wire jumper (C1, C2).
