3.2.4 Divider Unit (DIU)
The Divider Unit (DIU) is a component of the antenna coupling system and is used for the
distribution of the signals received by all antennas onto the installed CHUs.
Different DIUs are used in the DIB-R5 advanced:
n
Ä
RX FILTER
n
Ä
Passive Divider Unit (PDU)
‒
only in case of a CHU expansion
The type used and the number of DIUs depends on the number of antennas and carriers.
