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, RDU 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. RDU consist of UDCU,
DTU, PAU and cavity duplexer like below figure and all modules are merged with one package.
