About Gallium Nitride Monolithic Microwave Integrated Circuit (GaN MMIC) Technology:
- It is a tiny, super-powerful computer chip built on a special chemical material that handles extremely high-frequency wireless signals without melting.
- It’s an all-in-one chip that combines tiny parts like transistors, resistors, and capacitors—onto a single piece of material to manage invisible wireless waves (microwaves).
- It is designed for applications up to the X-band frequency range.
- Origin: DRDO developed the GaN MMIC technology in 2024 and helped India quietly entered an elite club of seven countries: US, Russia, France, Germany, South Korea and China.
Why is GaN important?
- It is a material with exceptional thermal and electrical properties, making it critical for advanced defence applications such as sensors, radars, satellites, and missiles.
- A single indigenous 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.
- Gallium Nitride (GaN) is considered one of the most important semiconductor technologies for modern defence systems.
- It offers: Higher power output, Better energy efficiency, Faster signal processing, Reduced size and weight, Improved thermal performance, Greater reliability in harsh environments.
