DRDO develops indigenous GaN tech for radars
India's Defence Research and Development Organisation (DRDO) has developed indigenous Gallium Nitride (GaN) technology for high-frequency defence systems, including next-generation radars and electronic warfare systems. The technology involves advanced components that enable the generation, amplification, reception, and control of high-frequency signals, with applications in radar, electronic warfare, communications, intelligence, surveillance, reconnaissance, and unmanned systems.
A single GaN chip, measuring 3.5 x 3 mm, can deliver up to 30 watts of power and operate at speeds 300 times faster than silicon. This development, highlighted in the Ministry of Defence's annual report for FY25-26, is part of efforts to achieve self-reliance in semiconductor technology through the Innovations for Defence Excellence (iDEX) initiative.
