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 exceed 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 calibration and detection of the transmit power level at the 50 Ohm 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 3 dB, a value configurable at production (e.g. if the gateway Tx power is +20 dBm max., the max. total Tx power will be +23 dBm).
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.
