RANsemi has launched the RNS805-RU-BB, a fully integrated baseband board targeting the development of 5G/4G Open RAN radio units (O-RUs) for manufacturers and system integrators developing next-generation O-RUs for complex multi-band, multi-operator deployments.

The 165 × 170-mm plug-and-play baseband board combines RANsemi’s RNS805 O-RU SoC with Texas Instruments’ AFE7769D 4T4R multi-band analog front-end (AFE) radio frequency (RF) transceiver solution. The combination supports the Split 7.2 architectures and all 5G FR1 bands from 600 MHz to 6 GHz.
The O-RU SoC and the 4T4R multi-band AFE RF transceiver solution provide a compact and flexible baseband platform that integrates seamlessly with various RF front-end modules. Supporting indoor small cells to outdoor macro units, the board provides a complete Cat A Split 7.2 baseband solution that integrates digital pre-distortion (DPD), GNSS/IEEE1588/SyncE timing synchronization, and support for TDD and FDD modes.
Supporting eCPRI fronthaul through SFP28 for 10/25GE or 10GE copper Ethernet, it includes a discrete RF front-end interface for flexible power amplifier configurations across deployment types. RJ45 and USB debug interfaces support Power over Ethernet and 12-V auxiliary power.
Designed for both standalone deployment and dual-board cascading for more complex radio units, the board is available for lab testing and commercial implementations and includes a complete 5G NR and LTE radio unit software license with full management, control, synchronization, and user-plane functions.
