IDRF I/O Details
The UBS Macro BTS antenna I/O equipment consists of the IDRF (Integrated Duplexer and RX
Filter) with dual directional couplers for each antenna port.
The UBS Macro BTS frame is equipped with one IDRF per sector antenna.
The IDRFs are passive devices and therefore do not require DC input power for operation.
The BTS Antennas connect to the front of the IDRF while the BTS frame equipment connects to
the rear of the IDRF .
RF test equipment can be connected to the directional couplers located on the front of the IDRF .
These ports allow RF signal monitoring of the antenna paths as well as RF signal injection into
the BTS equipment antenna paths.
See the applicable Figure 1 -5 or Figure 1 -6 for IDRF I/O connectors location and details.
