SOI RF Switches and Digital Step Attenuators – Qorvo® (Nasdaq: QRVO), a leading global provider of connectivity and power solutions, announced a new portfolio of silicon-on-insulator (SOI) RF switches and digital step attenuators (DSAs) designed for defense, aerospace and infrastructure customers. This new portfolio simplifies RF system design, reduces BOM complexity and accelerates integration in wideband systems.
These new solutions address growing system demands for broader frequency coverage, agile signal routing and simplified integration—without the complexity of legacy GaAs-based RF control component approaches or multi-vendor RF control chains. With TTL-compatible control that eliminates the need for a negative voltage rail, Qorvo’s SOI portfolio helps designers simplify biasing networks, reduce BOM count and streamline board layouts while maintaining the fast-switching speeds, high isolation and high linearity required in defense and aerospace applications. The portfolio gives designers a simpler alternative to legacy RF control approaches that require negative bias rails, multiple control components and more complex board-level integration.
“Customers are looking for ways to simplify RF control architectures without sacrificing the switching speed and RF performance required in modern defense systems,” said Doug Bostrom, general manager of Qorvo’s Defense and Aerospace business. “By eliminating the need for a negative voltage rail, our SOI portfolio helps reduce design complexity, streamline integration and provide a faster path from design to deployment.”

Unlike conventional approaches that rely on multiple narrowband components or mixed-vendor solutions, Qorvo’s SOI portfolio enables designers to standardize switch and attenuator functions into a scalable RF control platform. This reduces routing complexity, minimizes calibration effort and accelerates design reuse across programs. Compared to legacy GaAs switches, Qorvo delivers simpler biasing and easier integration while maintaining the RF performance needed for modern defense and aerospace systems. Compared to discrete multi-part RF control chains, designers can reduce BOM complexity, board space and integration burden while improving signal integrity and simplifying future upgrades.
The portfolio aligns with key industry trends including wider bandwidth radar and EW systems, more agile signal routing requirements and increasing pressure to reduce SWaP while accelerating time to market. By combining simplified control integration, fast switching, high isolation, strong linearity and flexible digital control, Qorvo enables designers to modernize RF control architectures without increasing system complexity.
The products are available now from Qorvo and authorized distributors.
Qorvo will showcase its latest RF innovations, including this SOI portfolio, at IMS2026, June 7–12 in Boston, Booth 20036.
