Huawei 02314425 M850-family GSM base station (BTS3012/BTS3006 generation) Radio Frequency Module

The 02314425 is a Huawei DTRU (Double Transceiver Unit) board for the M850-family GSM base station, confirmed via Huawei BTS3012/BTS3006 equipment documentation and reseller listings referencing the DTRU M850/M1800 board range. The DTRU is a combining unit that handles RF transceiver duplexing and combining functions within the base station cabinet, allowing multiple carrier signals to share antenna feeder paths efficiently. It is a core RF-path board on M850-class Huawei GSM sites, sitting alongside DDPU/DFCU combining boards depending on the specific site configuration (S4-and-smaller sites typically use DDPU, while S5-S8 sites use DDPU+DCOM or DFCU combinations). Operators maintaining legacy M850 GSM sites keep DTRU boards as maintenance spares since replacement stock for this generation of Huawei RF hardware has become harder to source 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.
