Singapore Advancing Indigenous GaN Technology For Radar, EW Systems

Singapore’s DSO National Laboratories is developing indigenous gallium nitride transistor technology for the radio-frequency transmitters used in military radar and electronic warfare systems. Gallium nitride can support high power density in radio-frequency electronics, making it relevant to transmitters that must deliver substantial power from compact modules. Singapore’s Ministry of Defence highlighted DSO’s wider work on field-proven transmitters for synthetic aperture radar and electronic warfare in its 2026 Defence Technology Prize materials, while the transistor development addresses the components that underpin such transmitters and the country’s capacity to design them domestically.
