Sierra Single-Chip Radio SoC Powers Next-Gen SAMJI Macro O-RU

Sierra’s advanced digital pre‑distortion (DPD) enables Samji Electronics to deliver exceptional macro RF performance while maintaining very low power consumption for cost‑effective network deployments. By significantly reducing radio power consumption and thermal management requirements while meeting spectral emissions targets with margin, Sierra enables a smaller and lighter radio design that simplifies installation and lowers total cost of ownership. In addition, Sierra’s full‑featured, production‑ready software platform helped streamline development, reduce integration risk, and accelerate Samji Electronics’ time‑to‑market.

“Selecting the Sierra platform allowed us to deliver a macro radio that combines high performance, outstanding efficiency, and a compact form factor,” said Taehoon Lee, CEO of Samji Electronics. “The maturity and scalability of the software platform give us a strong competitive advantage and allow us to respond quickly to evolving customer and market needs.”

“We are pleased to support Samji Electronics with our Sierra platform as they bring their next‑generation macro radio to market,” said Puneet Sethi, Senior Vice President of MaxLinear’s Network Infrastructure & Carrier BU. “Sierra’s high‑performance DPD, proven software, and scalable architecture helps customers like Samji Electronics to accelerate development of class-leading, efficient, carrier‑grade radio solutions.”

MaxLinear will host a live demonstration of Samji Electronics’ SNOO2-44N28 Macro Radio powered by the Sierra platform at the upcoming Mobile World Congress 2026 (MWC 2026) trade show (Hall 2, Stand 2L8MR). Attendees will be able to see the unit in operation and experience the platform’s performance, efficiency, and compact implementation firsthand.
