Barcelona, Spain – (BUSINESS WIRE) – March 2, 2026 – MaxLinear, Inc. (Nasdaq: MXL), a leading provider of wireless infrastructure solutions, today announced that it will showcase a growing range of commercially available Open RAN Radio Units (O-RU) based on its Sierra single‑chip radio SoC at Mobile World Congress (MWC) 2026 in Barcelona.
Attendees visiting meeting room 2L8MR in Hall 2 will see demonstrations of several new Sierra-powered O-RUs, including the Pegatron PR2850 Macro O-RU, Samji SNOO2-44N28 Macro O-RU, and Zenlynx RRU4401S Indoor O-RU. MaxLinear will also demonstrate Sierra’s Passive Intermodulation (PIM) cancellation technology, enabling development of smaller and lighter Frequency Division Duplex (FDD) Massive MIMO O-RUs.

Sierra is MaxLinear’s highly integrated radio SoC designed to power carrier‑grade radio units. Available as either 8T8R or 4T4R building blocks, Sierra combines dense RF integration with advanced digital signal processing, including Digital Pre‑distortion (DPD), Crest Factor Reduction (CFR), PIM cancellation, and a multi-port O-RAN 7.2x fronthaul interface to offer a complete solution for more compact, power‑efficient, and scalable radio designs across a wide range of deployment scenarios.

Sierra’s advanced DPD significantly improves PA energy efficiency while meeting spectral emission masks with margin, enabling OEMs to develop smaller, lighter, and more power-efficient radio units.
The Sierra-based radios being exhibited by MaxLinear at MWC are:

• Pegatron PR2850 Macro O-RU: Pegatron 5G’s latest carrier-grade macro radio for Open RAN deployments is purpose-built for performance and flexibility. The PR2850 combines high output power, TDD and FDD multi-band support, and advanced MIMO capabilities. Enabled by MaxLinear’s Sierra Radio SoC, the PR2850 delivers high performance in an ultra-compact form factor with low power consumption, helping accelerate the global adoption of open, intelligent, and sustainable 5G networks. 

 

• Samji SNOO2-44N28 Macro O-RU: Samji’s next-generation macro O-RU is powered by MaxLinear’s Sierra Radio SoC, delivering exceptional RF performance while maintaining very low power consumption to support cost-effective network deployments. MaxLinear is hosting a live demonstration of the SNOO2-44N28 at MWC 2026.

 

• Zenlynx RRU4401S Indoor O‑RU:  The RRU4401S addresses the growing demand for high‑performance, energy‑efficient indoor coverage. Zenlynx designed its new indoor O‑RU around a highly integrated radio architecture that prioritizes for compact form factor, very low power consumption, and deployment flexibility. By leveraging the Sierra single-chip radio platform, Zenlynx can deliver an indoor radio solution optimized for enterprise, venue, and neutral‑host environments where scalability and operational efficiency are critical.

At MWC 2026, MaxLinear will demonstrate these radios as well as Sierra’s PIM cancellation performance in Hall 2, meeting room 2L8MR.
