GaN RF Power Density Aims for 5x as DARPA Advances THREADS to Phase II - xenospectrum.com

The U.S. Defense Advanced Research Projects Agency (DARPA) has advanced its THREADS program to Phase II, aiming to significantly improve RF device power density and thermal management. Led by BAE Syst... Read original →

DARPA's THREADS program advancing to Phase II marks a pivotal step toward practical deployment of GaN RF power density improvements. With goals of fivefold power density gain and eightfold thermal resistance reduction, the initiative targets critical bottlenecks in military radar systems. Led by BAE Systems and FAST Labs, this effort pushes wide-bandgap semiconductors into operational defense platforms, directly impacting upstream chip fabrication and downstream system integration. The program’s success could redefine global supply chains for high-power RF devices, especially in the U.S. market. International competitors, including European and Asian players, are likely to accelerate their own R&D efforts to mitigate risks of technological displacement. The initiative also signals a strategic pivot toward domestic semiconductor resilience, with implications for manufacturing costs, thermal management materials, and long-term system scalability. This move could catalyze broader shifts in defense electronics, potentially reshaping global competitive dynamics in next-generation radar technologies.
