Marki Microwave Acquires LintrinsIC Semiconductors to Advance High-Power RF Switching Capabilities

Why It Matters

The move gives Marki a competitive edge in high‑performance RF switching, a critical bottleneck for next‑generation radar, electronic warfare and 5G mmWave systems, while offering customers a consolidated supplier for complex signal‑chain components.

Key Takeaways

• Marki adds 5‑50 W, 1 ns SOI CMOS switches to portfolio
• FastSwitch technology operates up to Ka‑Band for 5G mmWave
• Acquisition creates single‑source supplier for RF mixers, amplifiers, switches
• Founder Cameron Hill brings DARPA‑backed research and patents

Pulse Analysis

High‑power, ultrafast RF switching has become a linchpin in modern radar, electronic warfare and 5G mmWave infrastructure. Silicon‑on‑insulator (SOI) CMOS processes enable the FastSwitch™ platform to deliver nanosecond‑level transition times while handling up to 50 watts, a combination that traditionally required discrete, bulkier technologies. By pushing these capabilities into the Ka‑Band, LintrinsIC addresses the bandwidth and latency demands of next‑generation defense and satellite communications, where every nanosecond can affect detection range and data throughput.

Marki Microwave’s acquisition aligns with a broader industry trend toward single‑source, end‑to‑end signal‑chain solutions. Integrating FastSwitch switches with its existing portfolio of mixers, amplifiers, power dividers and filters reduces design complexity for OEMs and shortens development cycles. Customers benefit from a unified engineering support structure, streamlined procurement, and the assurance that component interfaces are optimized for performance and reliability. This strategic expansion also opens new revenue streams for Marki, positioning it to capture a larger share of the defense and telecom markets that are rapidly upgrading to high‑frequency, high‑power architectures.

The deal underscores the growing commercial viability of DARPA‑seeded semiconductor innovations. While the purchase price remains private, the willingness to invest in a company founded only in 2021 signals confidence in the scalability of SOI CMOS RF switches. As 5G networks densify and defense budgets prioritize electronic‑warfare capabilities, demand for compact, power‑efficient, and ultra‑fast switching solutions is set to rise. Marki’s enhanced offering could accelerate adoption across satellite constellations, phased‑array radars, and future 6G research, reinforcing its role as a pivotal supplier in the high‑frequency ecosystem.
