/ XSNSIXI 129/1551-LZA 701 0001 Uen
CBC/ XRX/M ( Kai Lian) 2011-05-05 F
Prepared (also subject responsible if other) No.
Approved Checked Date Rev Reference
Note: The maximum distance between the RBS and the BBS must not
exceed 10 meters to prevent damage from, for example, lightning.
Bias injector
The bias injectors are used to provide the TMA with DC power from the
TMA-CM, over the RX/TX feeder cables. In the RBS 2106, the bias injector
is mounted between the antenna feeder and the CDU. In the RBS 2106i and
RBS 2106 V3, the bias injector is mounted between the antenna feeder and
the antenna connection field.
Number of units: 0 – 12
DC/DC Converter
The DC/DC converter can supply 48 V DC power to transmission equipment
in the TM compartment. It converts +24 V DC to 48 V DC.
Number of units: 0 – 2
DC Filter
The DC filter is the interface between a +24 V DC external battery, and the
IDM inside the RBS.
The DC filter has the following main functions:
• ElectroMagnetic Compatibility (EMC) filtering
• Connection of +24 V DC to the cabinet
• Distribution of +24 V DC power to the IDM
Number of units: 0 – 1
ddTMA
The ddTMA is to be mast-mounted and placed close to the antenna. It improves
the receiver sensitivity. The ddTMA saves feeder cables by duplexing RX and
TX signals to the same cable.
Number of units per cabinet: 0 – 6
ESB
TG synchronization is the technology used to expand one RBS 2106 cabinet
with another RBS cabinet in the same cell. The External Synchronization Bus
(ESB) is the cable connected between the DXUs.
Number of units: 0 – 1
