How MaxLinear Advances FDD Massive MIMO with Next‑Gen Wireless Tech

Why It Matters

The technology enables operators to deploy scalable FDD massive MIMO networks at reduced cost and power, accelerating 5G capacity growth and improving end‑user performance.

Key Takeaways

• MaxLinear showcases integrated Wi‑Fi 7, DOCSIS 4.0, and 5G solutions
• Sierra chip reduces radio power using industry‑leading DPD technology
• New macro 4TR radio delivers 80 W TX in smaller footprint
• PIM cancellation eliminates ceramic duplexer interference for FDD massive MIMO
• Digital DSP engine enables cost‑effective, lightweight FDD massive MIMO radios

Summary

At the Mobile World Congress in Barcelona, MaxLinear highlighted its next‑generation wireless portfolio, emphasizing the Sierra mixed‑signal ASIC that targets FDD massive MIMO deployments.

The company demonstrated a suite of integrated products—including a Wi‑Fi 7 single‑chip, DOCSIS 4.0 modem, and a macro‑4TR radio that outputs nearly 80 W per transmitter while occupying a fraction of the traditional footprint. Central to the showcase was the Sierra chip’s industry‑leading digital predistortion (DPD) that slashes power consumption in radio units, and a new PIM‑cancellation engine that mitigates interference from ceramic duplexers.

In the live demo, Jerry Ponid showed how the PIM‑cancellation algorithm detects the spurious signal generated by a ceramic duplexer and drives it down to the noise floor, restoring clean constellation diagrams and improving EVM. He noted, “To make 5G‑grade FDD massive MIMO viable, we must replace bulky cavity filters with ceramic duplexers and eliminate their PIM through digital cancellation.”

By removing costly, heavy cavity filters and reducing power draw, MaxLinear’s solution promises lighter, cheaper base‑station radios that can handle the projected 100 % year‑over‑year uplink growth. Operators stand to accelerate 5G rollouts while delivering better indoor user experience at lower CAPEX and OPEX.
