Huawei 02314689 M850-family GSM base station (BTS3012/BTS3006 generation) Radio Frequency Module

The 02314689 is a Huawei DDPM board for the M850-family GSM base station, part of the same combining/duplexing-unit board family as the confirmed DTRU and DDPU boards documented elsewhere in this range. Based on Huawei’s M850/M1800-family RF naming convention, the ‘DP’ prefix pattern in this board family (as seen in the confirmed DDPU) denotes a duplexing function within the cabinet’s RF signal path, working alongside the DTRU transceiver unit to route carrier signals to the antenna feeder system. The precise distinction between DDPM and the related DDPU/DDCM/DSCM boards in the same family is not independently documented beyond their shared RF combining-unit role, so exact function should be confirmed against your site’s build sheet if the distinction matters for your application. Operators maintaining legacy M850 GSM sites keep boards like this as spares as the platform ages out of active production. Tech-Star (UK-based, shipped worldwide) supplies this as a tested spare.
