CETC delivers 5M gallium nitride chips for 6G space-ground network

China has achieved a milestone in semiconductor and 6G technology by delivering 5 million gallium nitride (GaN) chips to power smart terminals for a space-air-ground integrated network. Developed by the US-sanctioned No 55 Research Institute of China Electronics Technology Group Corporation (CETC) and its subsidiary Nanjing Guobo Electronics, these third-generation semiconductors are the first mass-produced GaN chips for commercial 6G use. The chips leverage a silicon-based platform and are destined for applications like high-end smartphones and mobile law enforcement devices, filling gaps in cellular coverage via satellite signal supplementation.

According to state media, the chips form the fundamental backbone for next-generation 6G communications, commercial space programmes, and the low-altitude economy. IDC analyst Cui Kai noted their potential for satellite signal filling where traditional cellular networks are unavailable. China, as the world's largest gallium holder and exporter, maintains strict export controls on the rare metal, adding geopolitical weight to this development. The delivery signals a strategic push to lead in 6G infrastructure despite US sanctions, with implications for global telecom standards and supply chains.
