Chinese researchers have unveiled a groundbreaking supercooling technology for gallium nitride (GaN) semiconductors, potentially increasing the performance of high‑power radar systems by up to 40%, according to the South China Morning Post.

The new chips are designed to operate under extreme power loads in the X‑band and Ka‑band frequencies, which are essential for advanced radar systems, satellite communications, and next‑generation wireless networks. GaN-based radar systems, which already feature prominently in China’s most advanced stealth aircraft, could see significant enhancements in efficiency and detection range.

The innovation tackles a longstanding challenge in semiconductor design: heat management. By dramatically improving cooling efficiency, these chips can handle higher power outputs without performance loss or damage, marking a major leap in the capabilities of domestic radar and communications hardware.

Experts note that this development not only strengthens China’s defense technology but also lays the foundation for high‑performance, next-generation wireless networks and satellite systems, as GaN semiconductors are increasingly used in both military and civilian applications.
