Abstract
The utility model discloses a lightning protection system used under the co-site condition of a 3rd-generation (3G) base station and a 2nd-generation (2G) macro base station. The lightning protection system comprises a base station room, a 2G transceiver, a 3G transceiver and a common antenna feeder, wherein the 2G transceiver and the 3G transceiver are arranged in the base station room, the common antenna feeder is arranged outside the base station room, a communication interface of the 2G transceiver is electrically connected with a path combiner through a feed wire and an external surge protection device (SPD), a built-in SPD of the 3G transceiver is electrically connected with the path combiner through a feed wire, and the path combiner is electrically connected with the common antenna feeder through the feed wire. The lightning protection system has the advantages that under the co-site condition of the 3G base station and the 2G macro base station, a feed wire SPD is arranged on a section from the 2G transceiver to the 3G transceiver, the insertion loss and the three-order intermodulation interference of the 3G transceiver are reduced through regulating the installing position of the feed wire SPD, the 2G intermodulation interference is effectively protected, the feed wire attenuation is reduced, meanwhile, the primary feed wire SPD is saved, and the system cost is reduced.
Description
Technical field
The utility model relates to the mobile communication base station room, especially relates to the anti-thunderbolt system when being used for NodeB and 2G macro base station and standing altogether.
Background technology
The macro base station that is used for mobile communication at present, in order to protect base station transceiver in the safe operation of when thunderbolt, feeder line SPD (SPD: surge protector) when the 2G base station, be mounted in the feeder cable transducer after, and independent the installation; On this basis; When NodeB and 2G macro base station are stood altogether, will increase mixer owing to need shared antenna feeder, this just makes 2G feeder line and 3G feeder line close after the road; Because original 2G feeder line has been installed feeder line SPD; Add mixer, and the 3G transceiver in the feeder line SPD of system, cause insert loss increase, signal to noise ratio variation and cause communicating by letter undesired.Simultaneously because the existing feeder line SPD of 3G device interior, so for the 3G transceiver many again one-level feeder line SPD, and this installation method can produce bigger third order intermodulation and disturbs.
Summary of the invention
The utility model purpose is to provide a kind of and inserts loss and the feeder line attenuation reduces, low anti-thunderbolt system when being used for NodeB and 2G macro base station and standing is altogether disturbed in third order intermodulation.
For realizing above-mentioned purpose, the utility model can be taked following technical proposals:
Anti-thunderbolt system that the utility model is said when being used for NodeB and 2G macro base station and standing altogether comprises the room, base station, is arranged on 2G transceiver and 3G transceiver in the room, said base station, and is arranged on the shared antenna feeder outside the room, base station; The communication interface of said 2G transceiver is electrically connected with mixer through feeder line and external surge protector, and the in-built electrical surge protector of 3G transceiver is electrically connected with said mixer through feeder line, and mixer is electrically connected with said shared antenna feeder through feeder line.
The utility model advantage just is when stand altogether in distributed base station and grand station; Take to section between the mixer feeder line SPD to be installed at the 2G transceiver, through the installation site of adjustment feeder line SPD, thereby the insertion loss and the third order intermodulation that have reduced the 3G transceiver are disturbed; Effectively protected the 2G transceiver; Reduce the feeder line attenuation, saved one-level feeder line SPD simultaneously, reduced system cost.
