Huawei 022HEJ BBU3900/BBU3910 (Multi-mode) Base Station Module

The Huawei 022HEJ is a UBBPd3 (Universal Baseband Processing Unit, d3 revision) module for use in Huawei’s wireless base station infrastructure. This baseband unit handles digital signal processing functions including modulation, demodulation, encoding and decoding for mobile network communications, connecting to the associated radio units over CPRI optical fibre. The UBBPd3 is deployed within Huawei’s BBU3900/BBU3910 baseband units, supporting LTE and multi-mode network configurations depending on the board’s software load, and serves as a core processing component working alongside the main control board and RF modules. This module forms part of Huawei’s distributed base station architecture commonly deployed in mobile network operator infrastructure. As network technologies evolve, UBBPd3 units continue to serve in established LTE and multi-mode deployments and are sought for network maintenance, capacity expansion and spares provisioning. Tech-Star (UK-based, shipped worldwide) supplies tested UBBPd3 boards. Get in touch to confirm compatibility and check current stock.
