Secondary Remote Access Units
A Secondary Remote Access Unit (SRAU) receives FWD IF signals from the MRAU, using 75 CATV cable. The
SRAU converts the IF signals to RF and sends them to a passive RF antenna using 50
 coaxial cable. The SRAU,
through the MRAU, also receives configuration information and power from and sends its status information to
the IFEU.
The SRAU receives REV RF signals from a passive RF antenna using 50
 coaxial cable. It converts the signals to
IF and sends them to the MRAU using 75
 CATV cable.

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 2 on page 11.
4 SECONDARY FWD connector F connector port Connects to one of the MRAU FWD SECONDARY ports (1 -
3) via CATV cable.
(1) The 700 MIMO SRAU does NOT have an RF SMA cable; it has two Antenna ports.
