In view of the modernization of the AWACS fleet, IES has created a "UHF Integrated Cositing Unit", called ICU, designed with the aim of improving the technical characteristics of UHF systems in on-board communications.

This unit provides signal amplification in the 225 ÷ 400MHz range, with an output power of 50 W and an input signal of 2 W.

This amplifier is equipped with a fast tunable filter module in the 225 ÷ 400MHz range that uses PiN-Diode array technology; with a 10-bit interface that provides high tuning accuracy. The Filter module supports medium power RF signals, and provides fast switching speed and small size, thus overcoming the technical limitations typical of other technologies (Manual Tuning Filters or Filter Bank).
