Main Remote Access Units
The Main Remote Access Unit (MRAU) receives FWD IF signals from an IF Expansion Unit (IFEU), which is part
of the Spectrum Expansion Module Group, using 75
 CATV cable. The MRAU converts the IF signals to RF and
sends them to a passive RF antenna using 50
 coaxial cable. The MRAU also receives configuration information
and power from and sends its status information to the IFEU.
The MRAU receives REV RF signals from a passive RF antenna using
50 coaxial cable. It converts the signals to
IF and sends them to the IFEU using 75
 CATV cable.

50 RF SMA-to-SMA cable
(or 50 RF N-to-SMA cable)
Connects two RF bands together so there is only one
N-type connector on the RAU to connect to an antenna.
2 Antenna port(s) 50 N-type connector Connects to an antenna. See Table 2 on page 11.
3 FWD IF IN connector F connector port Connects to the IFEU FWD Module IF OUT connector
via CATV cable.
4 FWD SECONDARY PORTS (1 - 3) F connector ports Connect to a SRAU SECONDARY FWD connector via
CATV cable.
5 REV SECONDARY PORTS (1 - 3) F connector ports Connect to a SRAU SECONDARY REV connector via
CATV cable.
6 REV IF OUT connector F connector port Connects to the IFEU REV Module IF IN connector via
CATV cable.
(1) The AWS/PCS MRAUs do NOT have an RF SMA cable—they have two Antenna ports.
