5G Antenna Calibration IDU
IDLP-5GAO1-IDUOO-OPN
Item 6423
The Calibration IDU provides an interface between a 5G gateway modem and the outdoor antenna (ODA). The IDU
function is to compensate for antenna gain and coaxial cable losses to ensure that transmit power levels do not ex-
ceed a permitted EIRP limits while optimum sensitivity is maintained for Rx signals.
The IDU contains a signal source used only during calibration and high-speed power detectors used for both calibra-
tion and detection of the transmit power level at the 50R ports. Calibration is performed automatically after a power
cycle. During calibration, internal variable attenuators are set to control overall system gain level (IDU + Cabling +
ODA) to a maximum of 3dB, a value configurable at production (e.g. if the gateway Tx power is +20dBm max., the
max. total Tx power will be +23dBm).
The IDU is supplied with a dual SMA male-SMA male cable to connect with the 5G gateway. For connecting the IDU
and the ODA, a 6GHz-rated RG6 cable is recommended.
