[embodiment]
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
See also Fig. 2, the integrated multisystem access device of the utility model comprises filtering integral unit (11 or 12) and back level mixer 2.Said filtering integral unit (11 or 12) both can be the filter 12 that only a single frequency band signal is carried out Filtering Processing, also can be the frequency range mixer 11 that two different frequency range signals are carried out filtering and integrate.
For downstream signal; Described filtering integral unit (11 or 12) is used to insert the input of a single frequency band signal or a plurality of different frequency range signals; Signal after its filtering is integrated outputs to the back level mixer 2 that electrically connects with it, exports after the signal that back level mixer 2 comes all each filtering integral unit (11 or 12) transmission closes the road.
Well-known; Because of the multisystem access device is a reciprocal devices; So for upward signal; The descending process contrary of its up process and aforementioned downstream signal, the upward signal that level mixer 2 gets into from the back will be outputed to each filtering integral unit (11 or 12) along separate routes, by the upward signal output of each filtering integral unit (11 or 12) with corresponding band.
Further please combine Fig. 3; The integrated multisystem access device of the utility model highly is integrated in the cavity 8; Cavity 8 set inside have a plurality of plates; One of them or a part of plate are used for integrated described filtering integral unit (11 and 12), and another or another part plate are used for integrated described back level mixer 2, depend on actual need and decide; Said back level mixer 2 all can be integrated on one or more plates with said filtering integral unit (11 or 12) as required, electrically connects each other between different plates to satisfy back level mixer 2 and filtering integral unit (the 11 or 12) annexation on electric.Described plate can be circuit board, also can be meant other way of realization, and those skilled in the art should know this flexible transformation.
As shown in Figure 3; A plurality of filtering integral unit (11 or 12) and circuit board plate are integrated when cavity 8 inside; A plurality of information source side ports J1-J6 and an antenna feeder side ports J7 need be set on the cavity 8; Information source side ports J 1-J6 quantitatively is provided with corresponding to each downstream signal input (upward signal output) of said filtering integral unit (11 or 12), also be information source side ports J1-J6 respectively with the downstream signal input port electric connection of corresponding filtering integral unit (11 or 12); Antenna feeder side ports J7 is provided with corresponding to the downstream signal output (upward signal input) of said back level mixer 2, also is that the public port of antenna feeder side ports J7 and back level mixer 2 electrically connects.By this, through with the patching of information source side ports J1-J6 and antenna feeder side ports J7, can realize the electric connection of multisystem access device and external devices.
As shown in Figure 4; For some situation of different frequency range that belongs to identical standard and belong to the identical standard of different operators; As for DCS1800 of China Mobile and the DCS1800 of CHINAUNICOM; They occupy frequency ranges such as 1710-1725MHz/1805-1820MHz and 1745-1755MHz/1840-1850MHz respectively; Then can before the information source side ports of multisystem access device, utilize a mixer 52 that each frequency band signals is closed Lu Houzai and input in the corresponding filtering integral unit (11 or 12) through the information source side ports.This situation also can adopt electric bridge 51 to close the road; For example; China Mobile GSM 900 is occupied the 890-909MHz/935-954MHz frequency range, and the GSM900 of CHINAUNICOM then occupies the 909-915MHz/954-960MHz frequency range, can adopt electric bridge to close the road in this case.
This shows,, can further satisfy some specific demands that multisystem inserts at passive devices such as the preposition electric bridge of the information source side ports of integrated multisystem access device 51, mixers 52.
Further, as shown in Figure 5, assemble mutually with power divider 3 and form a junction network by integrated multisystem access device 1, integrated multisystem access device 2.This power divider 3 can adopt electric bridge to realize; Be preferably the high power electric bridge; The antenna feeder side ports J7 of said two multisystem access devices 1,2 all imports (upward signal output) corresponding electric connections of port with two downstream signals of power divider 3, and two other downstream signal output (upward signal input) port of power divider 3 then electrically connects with two air feedback unit ANT1, ANT2 respectively.Because power divider 3 and multisystem access device 1, the electric connection between 2 can adopt cable to be connected, therefore, can a plurality of multisystem access device 1,2 long-distance distribution formulas be placed, realize networking at a distance.In like manner, aforementioned setting at the preposition passive device of integrated multisystem access device is applicable to the multisystem access device 1,2 in this junction network too.
Comprehensive above-mentioned about the junction network of the utility model and the execution mode of integrated multisystem access device, can further sum up the advantage that the integrated multisystem access device of the utility model is brought:
Integrated design: use is total to chamber coupled modes height and is integrated in an inside cavity between filtering integral unit, back level mixer, needn't use any cable to connect.Each intermodule that changes conventional P OI adopts radio frequency cable line connected mode; Integrated design can reduce radio frequency cable line, cable joint usage quantity, provides cost savings greatly, simultaneously; Also reduce the loss that cable self brings, helped improving the complete machine index of POI.Conventional P OI adopts each module cascade; After cascade, need each module of debugging; Make each intermodule realize that optimum Match guarantees to arrive optimal parameter; Need not after the integrated multisystem access device assembled each module debugged and to satisfy index, significantly reduced human resources, saved production cost.
Extensive adaptability: the integral system access device has been contained present domestic three tame operators GSM commonly used, can cover the engineering actual conditions according to radio communication, adapts to actual access information source quantity.When operator's dilatation need increase source device, only need to add independent ancillary equipment and can accomplish function, need not to develop again novel POI; Actual field information source negligible amounts adopts traditional mixer or POI can't realize closing the road function again, only needs not connect matched load and can overcome the above problems inserting the information source joint on the integral system access device base station end panel.
Scheme development and flexible Application: 1) the integral system access device adds that peripheral passive device develops into other scheme; As add single antenna feeder port transmitting-receiving that 900MHz electric bridge, DCS frequency range mixer, 3G FDD mixer can be designed to contain all frequency ranges commonly used and close the cable scheme, as shown in Figure 5; 2) can close the integrated transmitting-receiving of deriving of cable scheme according to this transmitting-receiving and divide the cable scheme; 3) back level power distributing unit again 3 of other power dividers of cascade can develop and be many antenna feeders scheme (the engineering actual conditions are generally 3 ports or 4 ports); 4) internal module is designed to independent installation form, can be used as trunking and uses separately.
Although the utility model only provides above embodiment; But; Those skilled in the art in conjunction with common practise, should be able to associate more embodiment after reading over this specification; But the spirit of the not unconventional the utility model claim of such embodiment any type ofly is equal to replacement or simple modification all should be regarded as by the included embodiment of the utility model.
