MaxLinear will showcase a new line of Sierra‑powered Open RAN Radio Units (O‑RUs) at the Mobile World Congress in Barcelona, running from March 2 to March 5, 2026. The company will display the Pegatron PR2850 Macro O‑RU, the Samji SNOO2‑44N28 Macro O‑RU, and the Zenlynx RRU4401S Indoor O‑RU in meeting room 2L8MR of Hall 2, highlighting the compact, power‑efficient, and scalable design of the Sierra platform.
The Sierra SoC incorporates passive intermodulation (PIM) cancellation technology that eliminates the need for bulky cavity filters, enabling smaller and lighter frequency‑division duplex (FDD) massive MIMO O‑RUs. This technical advantage positions MaxLinear’s products as a compelling option for operators looking to expand uplink capacity and deploy multi‑band macro and indoor radios at scale.
In its most recent earnings release, MaxLinear reported Q4 2025 revenue of $136.4 million, a 48% year‑over‑year increase, and a non‑GAAP EPS of $0.19, beating analyst estimates of $0.18. The earnings beat was driven by a 79% jump in the Infrastructure segment, which now represents the company’s largest revenue contributor and reflects strong demand for data‑center connectivity and optical DSPs. Cost control and a favorable product mix also helped maintain margins during the period of rapid growth.
Market reaction to the earnings was mixed. While the company’s performance exceeded expectations, investors focused on the cautious Q1 2026 revenue guidance, which was slightly below analyst consensus. The guidance reflects management’s conservative outlook on near‑term demand, even as it signals confidence in maintaining high gross margins of 58%–61% for the first quarter of 2026.
Management emphasized the strategic importance of the Sierra platform. CEO Dr. Kishore Seendripu said, “We delivered 30% revenue growth year over year, driven by strong execution.” Senior Vice President Puneet Sethi added, “Sierra is already a proven carrier‑grade solution for single‑ and multi‑band macro radio units. By using PIM cancellation to eliminate bulky cavity filters, Sierra is enabling OEMs to build simpler, lighter FDD Massive MIMO radios that operators can deploy at scale to address the uplink demand challenge.”
The showcase underscores MaxLinear’s positioning in the expanding Open RAN market. Partnerships with Pegatron, Samji Electronics, and Zenlynx demonstrate market acceptance of the Sierra SoC, while the company’s focus on infrastructure and the Open RAN ecosystem signals a strategic pivot toward high‑growth segments that are expected to drive the next wave of 5G deployment.
