Combining system and filtering is the interface between transmitters and
the antenna system. The functions of the system are:
the antenna system. The functions of the system are:
•
Antenna system supervision support
•
RF filtering
•
Duplex filtering
The TX reference point X is defined as the point where the TX antenna
signal crosses the RBS border, that is, the connector for the antenna
feeder. See Figure 99 on page 260.
