3.2.4 Divider Unit (DIU)
The Divider Unit (DIU) is a component of the antenna coupling system and used for dis-
tributing a reception signal received by the antennas to the installed CHUs.
Different DIUs are used in the DIB-R5 flexibleTx:
n
The type used and the number of DIUs depends on the number of antennas and carriers.
