Colorado Springs, CO (February 13, 2025) – Frontgrade Technologies, a leading provider of mission critical electronics for aerospace and defense, has become the first company to successfully qualify to Class L standards its Gallium Nitride (GaN)-based DC-DC converter and complementary electromagnetic interference (EMI) filter. Under the Defense Logistics Agency’s MIL-PRF-38534 specification, Class L qualification verifies these devices’ ability to meet the most stringent performance requirements of space missions from Low Earth Orbit (LEO) through Geostationary Earth Orbit (GEO).
Frontgrade’s new isolated, single-stage converters leverage advanced GaN FET technology to provide spacecraft designers with the industry’s most efficient power conversion modules available today, offering 93% efficiency. With faster switching and improved performance, the company’s GaN DC-DC converter responds rapidly to dynamic power demands and provides multiple voltage outputs for maximum flexibility. This device is designed to convert power seamlessly from the bus to the point of load, ensuring optimal performance for current and future space applications.
“Launching an efficient power solution that has met rigorous Class L qualifications confirms that our GaN converter can reliably address the critical power management needs of next-generation satellites,” said Lorne Graves, Chief Technology Officer at Frontgrade Technologies. “With Frontgrade’s flight-ready modules and evaluation test boards, our customers can accelerate their development cycles to achieve on-time mission success.”
Flight and engineering modules, along with evaluation test boards, are now available, providing the essential tools for development, testing, and deployment in mission-critical spacecraft systems.
