Component Device Function
1 SECONDARY REV connector
F connector port
Connects to one of the MRAU REV SECONDARY ports
(1 - 3)
via CATV cable.
2 RF SMA cable
(1)
50 RF SMA-to-SMA cable
Connects two RF bands together when there is only one
N-type connector on the RAU.
For cases when there is an N-type connector for each RF band
(700MIMO or
PCS/AWS), there will not be an SMA cable.
3 Antenna port(s) 50 N-type connector Connects to an antenna. See Table 3 on page 11.
4 SECONDARY FWD connector F connector port Connects to one of the MRAU FWD SECONDARY ports (1 - 3)
via C
ATV cable.
(1) The 700 MIMO SRAUs does NOT have an RF SMA cable, and has two Antenna ports.
