5.3 RF Cabling with RU
The AW-100 transmitter output and diversity receiver inputs are connected to the Radio
Units, which contain the duplexer, LNA (Low Noise pre-Amplifier) and HPA (High Power
Amplifier) functions. Connect using RF jumper cables as shown in Figure 5-3.
Communication between the AW100 and the RU is accomplished with the Master / Slave
LAN cable (KDR45AE). This cable is connected from the AW100 RUIF port to the
Master port on the RU as shown in Figure 5.3.
Use only the cables supplied with the RU system for interconnection to the AW-100.
Cables are labeled for ease of installation. See Figure 5-4 for RF cable specification.

It is important to ensure transmit and receive connections are made correctly to prevent
damage or field operational problems such as:
- Damage due to transmitting into a receiver port
- Crossed over diversity receive ports
