Radio Configurations, RBS 2206
4.6.1 dTRU Topology
Configuration of Hybrid Combiner
The dTRU can be configured with or without the hybrid combiner,
using two external cables.
RX Signals Distributed from Two Ports
The RX signals can be distributed from the RX1 and RX2 ports to all
four receivers when both transceivers are connected to the same antenna
system.
