Description
Technical field
The present invention relates to a kind of telecommunication transmission equipment, be specifically related to a kind of signal of communication multisystem cable combination equipment.
Background technology
China's existing mobile communication network has the GSM900/DCS1800 of GSM900/DCS18001 CHINAUNICOM of China Mobile and PHS WLAN Digital Clustering and other communication systems of CDMA800 China Telecom and Netcom, also will build up WCDMA CDAM2000TD-SCDMA3G system successively.The outdoor location network signal can cover by base station separately, and indoor signal can not solve by traditional indoor covering system.It is more and more outstanding that yet each operator builds the problems such as repeated construction that covering system brought of oneself respectively.At such problem, the solution of channel platform that multisystem is closed (POI) has been proposed.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 CDMA GSM 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.But present POI equipment inner structure more complicated, the components and parts that relate to are more, the volume of equipment is bigger, and equipment in components and parts be passive device, can cause the insertion loss of POI like this.
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, components and parts are few, the little POI multisystem cable combination equipment of repeater of insertion loss of POI.
The present invention is achieved through the following technical solutions:
A kind of POI multisystem cable combination equipment of repeater includes signal port and is attached thereto the mixer that connects, and described signal port is connected with filter or duplexer signal input part; The output of filter or duplexer is connected with the input of signal amplifier, and the output of signal amplifier is connected with the input of multiplefrequency mixer, and multiplefrequency mixer is connected with antenna port by electric bridge.
A kind of POI multisystem cable combination equipment of repeater, described filter or duplexer and signal amplifier become one.
A kind of POI multisystem cable combination equipment of repeater, described duplexer are connected with two signal amplifiers, and filter is connected with a signal amplifier.
A kind of POI multisystem cable combination equipment of repeater, described multiplefrequency mixer are divided into up multiplefrequency mixer and descending multiplefrequency mixer; Two signal amplifiers that described duplexer connected, the output of one of them signal amplifier is connected with the input of up multiplefrequency mixer, and the output of another signal amplifier is connected with the input of descending multiplefrequency mixer; The signal amplifier that described filter connected, its output is connected with the input of descending multiplefrequency mixer.
A kind of POI multisystem cable combination equipment of repeater, described up multiplefrequency mixer are up five frequency combiners; Described descending multiplefrequency mixer is descending seven frequency combiners.
A kind of POI multisystem cable combination equipment of repeater, described signal amplifier are the repeater.
By with above-mentioned art scheme as can be seen, the present invention has following beneficial effect fruit;
1, performance index have significantly been optimized.Main component part has activated amplifier and passive duplexer filter among the present invention, and it is become one, and the insertion loss of POI is little like this, 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 of active passive duplexer, young pathbreaker's electric bridge is put into antenna and closes the road again simultaneously, has so just significantly reduced number of devices and volume.
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.
Table 1
Table 2
With the contrast of the performance index shown in table 1 and the table 2 as can be known, the lossless decay of the present invention, passband fluctuation is little, and return loss is little, and band is outer to suppress high, and main performance index such as the negative accent in three rank all have greatly improved.
