Qorvo® Simplifies RF Control with SOI Portfolio that Eliminates Negative Bias

Why It Matters

Eliminating negative bias rails streamlines RF system design, cutting cost and time‑to‑market for high‑performance defense and aerospace applications.

Key Takeaways

• Qorvo launches SOI RF switches and attenuators up to 30 GHz.
• New portfolio removes need for negative bias voltage rails.
• TTL‑compatible control cuts BOM count and simplifies board layout.
• Fast <50 ns switching, high isolation, and linearity meet defense specs.
• Products debut at IMS2026 in Boston, Booth 20036.

Pulse Analysis

The RF control market has long wrestled with complex biasing schemes and multi‑vendor part stacks, especially in defense and aerospace where performance margins are tight. Silicon‑on‑insulator technology offers a compelling alternative, delivering high‑frequency capability with the thermal and electrical isolation needed for rugged environments. By integrating switches and digital step attenuators on a single SOI platform, Qorvo reduces the number of discrete components, easing routing and improving signal integrity—key factors as radar, electronic warfare and satellite communications push toward wider bandwidths.

From a technical standpoint, Qorvo’s portfolio maintains the fast <50 ns switching times and high isolation traditionally associated with GaAs devices, while adding the benefits of TTL‑compatible control that removes the negative voltage rail. This simplification translates into lower bill‑of‑materials (BOM) counts, smaller board footprints and faster design cycles, directly addressing the industry’s SWaP (size, weight, and power) constraints. Engineers can also reuse the same SOI blocks across multiple programs, shortening calibration effort and enabling more agile upgrades as mission requirements evolve.

Strategically, the launch positions Qorvo as a front‑runner in the next generation of RF control solutions. With the portfolio now shipping and a live demonstration slated for IMS2026, the company is poised to capture market share from legacy GaAs suppliers and fragmented multi‑vendor solutions. The move aligns with broader defense procurement trends that favor integrated, low‑complexity components, suggesting a steady growth trajectory for SOI‑based RF control in both existing and emerging high‑frequency applications.
