The Department of Defense (DoD) is seeking proposals for the Small Business Innovation Research (SBIR) program focused on the development of vertical β-Ga2O3 devices for extreme environment power converters. The objective is to create radiation-tolerant and high-temperature compatible point-of-load (POL) converters that can operate in Low Earth Orbit (LEO) and hypersonic applications, addressing the need for devices that can withstand high voltages and temperatures while maintaining performance. These advanced power converters are crucial for enhancing the efficiency and reliability of RF amplifiers, pulsed RF communication, and pulsed laser diodes in demanding environments. The solicitation is set to open on May 28, 2025, with proposals due by June 25, 2025, and further details can be found at the DoD SBIR website.
