Description
Technical field
The utility model relates to communication equipment, particularly a kind of antenna subsystem.
Background technology
In Radio Network System, the antenna subsystem of communication base station comprises Remote Radio Unit (RRU, Radio Remote Unit) and antenna element, and RRU links to each other with antenna element, is used to realize the reception and the transmission of wireless signal.
The situation that has multiband networking at present comprises two (also claiming two-band) or is operated in the RRU of different frequency range more than two respectively in the promptly above-mentioned antenna subsystem.Fig. 1 is a kind of antenna element of two-band and antenna subsystem that RRU forms supported in the prior art, and what this illustrated is the situation of eight passages, also has the antenna subsystem of other port number in addition, enumerates no longer one by one at this.
RRU1 is operated in different frequency ranges respectively with RRU2, and its radio frequency interface all possesses 9 prevention at radio-frequency port, specifically comprises and corresponding 8 access ports of each passage and 1 calibration port, and the interface connector of each prevention at radio-frequency port adopts N connector.
The radio frequency interface of antenna element 11 also provides 9 prevention at radio-frequency port, specifically also comprises 8 access ports and 1 calibration port, and the interface connector of each prevention at radio-frequency port also adopts N connector.
Along separate routes mixer 12 provides 9 two-in-one/one-to-two devices, totally 27 prevention at radio-frequency port, and the interface connector of each prevention at radio-frequency port also adopts N connector.
As shown in Figure 1, prevention at radio-frequency port on prevention at radio-frequency port on the antenna element 11 and the mixer 12 along separate routes and being connected by radio frequency cable wire jumper between the prevention at radio-frequency port on the prevention at radio-frequency port on the mixer 12 and RRU1 and the RRU2 along separate routes need dock the joint of every wire jumper during construction, processing such as locking and junction waterproof.Antenna element 11 is installed on the pole 13 by accessory is installed, RRU1 and RRU2 also are installed on the pole 13 by accessory is installed, afterwards, RRU1 and RRU2 are connected by 9 corresponding on radio frequency cable 14 and the mixer 12 along separate routes prevention at radio-frequency port respectively, and other 9 prevention at radio-frequency port on the shunt mixer 12 pass through radio frequency cable 14 and are connected with 9 prevention at radio-frequency port of antenna element 11.
Antenna subsystem shown in Figure 1 is worked in the following manner: 9 tunnel radiofrequency signals of two frequency ranges of RRU1 and RRU2 output are exported to 9 prevention at radio-frequency port of antenna element 11 correspondences after shunt mixer 12 closes the road; Send RRU1 and RRU2 respectively to after the shunt of signal through shunt mixer 12 of 9 prevention at radio-frequency port outputs of opposite antenna element 11.
There is following defective in above-mentioned antenna subsystem of the prior art:
