3DB20420CB ALCATEL Alcatel MPT Radio Frequency Module

The Alcatel 3DB20420CB is a 13GHz Outdoor Unit (ODU) designed for microwave point-to-point transmission systems. This MPT-HQAM module operates in the 13GHz frequency band and provides the radio frequency interface for wireless backhaul applications, handling signal transmission and reception between microwave link endpoints.

This ODU is part of Alcatel’s MPT (Microwave Packet Transport) platform, engineered for telecommunications backhaul infrastructure. The HQAM designation indicates support for higher-order quadrature amplitude modulation, enabling efficient spectral utilisation for carrier-grade wireless transport networks.

The Alcatel MPT microwave platform represents legacy infrastructure that was widely deployed for mobile backhaul and fixed wireless access applications. While this equipment has been superseded by newer Alcatel-Lucent and Nokia platforms, existing installations continue to operate and require replacement components for maintenance purposes.
