3DB20375CB ALCATEL Alcatel Microwave Radio Radio Frequency Module

The Alcatel 3DB20375CB is a 23GHz Outdoor Unit (ODU) designed for point-to-point microwave radio transmission systems. This unit operates in the 23GHz frequency band and handles the RF transmission and reception functions for wireless backhaul links, converting baseband signals for over-the-air transmission.

23GHz ODUs are typically deployed in metropolitan and urban backhaul applications where licensed spectrum provides interference-free connectivity. These units form part of split-mount microwave radio systems, pairing with an Indoor Unit (IDU) to deliver high-capacity wireless links for mobile network backhaul, enterprise connectivity, and carrier Ethernet transport.

This is a legacy Alcatel microwave product from before the Alcatel-Lucent and subsequent Nokia acquisitions. While discontinued, these units remain in active service across established networks and are sought after for spares, maintenance, and network expansion where operators wish to maintain consistency with existing infrastructure.
