Product Overview
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
converts the IF signals to RF and sends them to a passive RF antenna using 50
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
the signals to IF and sends them to the IFEU using 75
