IN Brief:
- MaxLinear’s Trinity platform combines URX850 silicon with cloud-native backhaul software.
- The platform supports bidirectional wireless backhaul speeds up to 10 Gbps.
- The design integrates functions previously handled by multiple external components.
MaxLinear has launched Trinity, a wireless backhaul platform for 5G networks that combines its URX850 system-on-chip with cloud-native control software and AI-enabled link management.
The platform is designed to deliver carrier-grade bidirectional wireless backhaul speeds of up to 10 Gbps, targeting microwave and E-band radio systems used to connect cell sites and radio access equipment to the core network. Trinity integrates switching, quality-of-service handling, multi-link aggregation, timing, and encryption functions into the URX850 platform, reducing the number of external devices required in outdoor radio designs.
A cloud-native API framework gives equipment manufacturers a route toward software-defined and remotely managed radio architectures. The platform also supports the Open Compute Project Switch Abstraction Interface, allowing backhaul equipment to be developed with a more open software model.
Trinity can aggregate up to four microwave wireless links simultaneously, adapting to changing channel conditions as capacity, interference, or weather conditions shift. MaxLinear has specified rugged operation from -40°C to +85°C, reflecting the requirements of outdoor backhaul radios installed on towers, rooftops, and remote infrastructure.
Hardware-accelerated encryption is included to protect traffic across wireless transport links. The combination of secure packet handling, timing, link aggregation, and software control places more of the backhaul system inside the silicon platform, rather than spreading those functions across multiple board-level devices.
Mobile operators are under increasing pressure to add network capacity without making each site more complex or power-hungry. Dense 5G deployments need higher-capacity backhaul, but outdoor radio units still have strict limits on enclosure size, thermal dissipation, maintenance access, and installation cost. A design that replaces multiple devices with a more integrated SoC can reduce board area and power consumption while simplifying qualification.
The AI link-management element is aimed at a practical operating problem. Wireless backhaul links must cope with weather variation, spectrum congestion, changing traffic patterns, and line-of-sight constraints. Automated link control can help preserve capacity and service quality without requiring manual intervention every time conditions change at the site.
Backhaul radios are steadily becoming more software-defined, with silicon platforms expected to handle packet processing, security, timing, network control, and adaptation to changing link conditions. That shift brings telecom infrastructure closer to embedded system design, where hardware integration and software flexibility have to advance together.
OEM products based on Trinity are expected in the first half of 2027. By combining radio-adjacent control, packet handling, cloud management, and link automation, the platform gives backhaul manufacturers a more integrated foundation for the next stage of 5G transport equipment.
