Huawei 02315290 M850-family GSM base station (BTS3012/BTS3006 generation) Radio Frequency Module

The 02315290 is a Huawei DTRU (Double Transceiver Unit) board for the M850-family GSM base station, the same board type as material code 02314425 documented elsewhere in this range, confirmed via Huawei BTS3012/BTS3006 equipment documentation and reseller listings. As with other DTRU boards, it handles RF transceiver duplexing and combining within the base station cabinet, allowing multiple carrier signals to share antenna feeder paths efficiently, and sits alongside DDPU/DFCU combining boards depending on site configuration. The different material code from 02314425 likely reflects a different hardware revision or manufacturing batch of the same board type rather than a functional difference, though exact revision differences are not independently documented. Operators maintaining legacy M850 GSM sites keep DTRU boards as maintenance spares as the platform ages out of active production. Tech-Star (UK-based, shipped worldwide) supplies this as a tested spare. Get in touch with our team to confirm compatibility with your site configuration before ordering.
