Multiplexer2
This integrated combiner unit combines all low bands (<1
GHz) to one antenna connection and all high bands (>1
GHz) to a second antenna connection.
No combiner
If no
combiner is used, all amplifier outputs should be
connected directly to the individual antenna connectors
on the bottom of the enclosure

2.1.3 Function by unit
2.1.3.1 High Remote Drive Unit (HRDU)
When receiving TX signals from each band through Remote Optic, HRDU filters the signals and amplifies
them with High Power Ampifier. The unit also filters RX signals given through cavity filter and amplifies
them to send the signals to Remote Optic.In the unit, there is ATT to adjust gain. HRDU consist of UDCU,
DTU, PAU and cavity duplexer like below figure and all modules are merged with one package.

HRDU devices are varied for each frequency band , including the following:
