Northrop Grumman develops market-ready GaN chip for W-band RF in under six months - Semiconductor Today

Northrop Grumman has developed a market-ready gallium nitride (GaN) chip for W-band radio frequency applications in under six months, marking a significant advancement in high-performance semiconducto... Read original →

Northrop Grumman’s sub-six-month delivery of a market-ready W-band GaN RF chip compresses the traditional 18–24 month development cycle, triggering a cascade across the high-frequency semiconductor stack. Technically, it accelerates the obsolescence of GaAs and silicon LDMOS in military radar and LEO satellite terminals by enabling higher power density at 75–110 GHz. Compliance-wise, its integration into the DoD-backed DREAMS ecosystem embeds the supply chain within a ‘trusted foundry’ regime—likely extending export controls to 6G infrastructure components and raising barriers for non-U.S. players. Competitors like Raytheon and BAE Systems may respond with strategic acquisitions of GaN startups, while TSMC (Taiwan, China) and STMicroelectronics must fast-track 4-inch GaN-on-SiC yield certification. Over the next 12–24 months, W-band GaN will become a dual-use flashpoint; its cost-per-watt trajectory will dictate whether THz-based 6G access can realistically commercialize before 2030.
