This blog takes a look at HENSOLDT’s new long-term supply agreement with United Monolithic Semiconductors (UMS) for gallium nitride (GaN) semiconductors. It’s a move meant to secure high-performance radar components, shore up supply-chain resilience, and fuel growth in the global sensing market.
We’re diving into how the 900,000 GaN devices set for delivery by 2030 will power transmit and receive modules in HENSOLDT’s radar systems, especially the Spexer radar family. What does this mean for HENSOLDT’s standing as a next-generation system integrator? Let’s see.
Strategic partnership to secure GaN for advanced radar systems
UMS will deliver 900,000 GaN semiconductor components to HENSOLDT by 2030. These devices matter for amplifier performance, range, precision, and energy efficiency in transmit and receive modules.
HENSOLDT and UMS are working together on development and testing, focusing on the Spexer radar family. The collaboration stands out as a key strategy to strengthen supply-chain resilience, especially with global demand for sensor solutions climbing fast.
By combining development and ramping up manufacturing, HENSOLDT wants to lock in reliable supply as demand accelerates across defense, security, and airspace monitoring.
Key technical and strategic benefits
- Enhanced amplifier performance and higher power density for longer detection ranges.
- Improved energy efficiency and better thermal management in high-frequency radar modules.
- Co-development and testing to guarantee quality and compatibility across HENSOLDT’s radar platforms.
- Long-term supply certainty to support production planning and customer needs.
- Scalability for both small and large-volume production, keeping up with market demand.
Enhancing radar performance and the Spexer family
GaN devices are at the heart of modern radar transmit and receive modules. They boost efficiency, peak power, and switching speeds.
For HENSOLDT, that means broader detection ranges, sharper target resolution, and lower energy use in airborne and ground-based systems. The Spexer family, which anchors the company’s radar offerings, will benefit from this steady GaN supply and the ongoing joint development with UMS.
GaN-enabled modules also help create more compact and power-efficient radar solutions. Designers can pack advanced capabilities into smaller platforms, which fits HENSOLDT’s goal of merging radar, optronics, electronics, and AI-driven software into next-gen sensing systems for air defense and security.
GaN’s role in high-frequency sensing
- Higher switching speeds allow more agile waveform control and better Doppler processing.
- Greater linearity means clearer images and better target discrimination in messy environments.
- Thermal reliability supports longer missions and cuts down on cooling needs.
- Compatibility with GaAs platforms makes integration smoother across existing sensor setups.
Supply chain resilience and capacity expansion
HENSOLDT sees the GaN supply agreement as a smart way to toughen up against rising demand for sensor solutions. The company is expanding production capacity to keep customer supply steady as global sensor demand climbs, reinforcing its reputation as a reliable system integrator for defense and security.
Partnering with UMS—a known GaAs and GaN specialist with scalable capabilities—fits well with HENSOLDT’s manufacturing strategy. UMS operates out of France and Germany, putting them in a good spot to support both moderate and high-volume production for military-grade radar components.
Market context and capacity plans
- 900,000 GaN components committed through 2030 to keep radar production supplied.
- Expansion of capacity to keep up with the rising global demand for radar and sensor tech.
- Strategic collaboration that mixes product development with supply-chain risk management.
Company profiles and market context
UMS specializes in GaAs and GaN technologies. They offer scalable capabilities that work for both small and large production volumes.
HENSOLDT reported €2.46 billion in revenue and employed about 9,500 people in fiscal 2025. The company calls itself a next-generation system integrator that blends radar, optronics, electronics, and AI-driven software for air defense and security.
This agreement builds on a long-term collaboration between UMS and HENSOLDT in high-frequency applications. It also reinforces HENSOLDT’s leadership in the radar and sensing market—though, let’s be honest, the competition isn’t standing still.
