AOR Remote Drive Unit (RDU)
When receiving downlink signals for each band from the MRU’s R_Optic module, the RDU filters out-of-
band signals and amplifies them with the high power amplifier. The unit also filters uplink signals received
through the uplink antenna and amplifies them before delivering the signals to the MRU’s R_Optic module.
Only the 150 VHF / 450UHF RDU is available for the AOR used with the EXPRESS system.
NOTE:
The 150 VHF / 450UHF RDU can also adjust gain, but it does not come fitted with a cavity
filter capability. External duplexers may be required but are not provided by SOLiD.”
