New Delhi: India GaN Technology breakthrough has marked a major milestone in the country’s defence modernization efforts. India has successfully developed indigenous Gallium Nitride (GaN)-based Monolithic Microwave Integrated Circuit (MMIC) technology for advanced defence platforms.
According to information highlighted by the Ministry of Defence, the achievement was led by Dr Meena Mishra and her team at the Solid State Physics Laboratory (SSPL), helping India reduce dependence on foreign semiconductor technologies.
Details of India GaN Technology Breakthrough
India’s Defence Research and Development Organisation (DRDO) has achieved a significant breakthrough by developing indigenous Gallium Nitride (GaN)-based MMIC technology.
This achievement strengthens India’s capabilities in advanced defence electronics and supports the country’s push for self-reliance in critical technologies. The Ministry of Defence highlighted the achievement in its Annual Report 2025-26, recognizing it as a major advancement for defence modernization.
Who Is Dr Meena Mishra
Dr. Meena Mishra is an Outstanding Scientist and the Director of the Solid State Physics Laboratory (SSPL) under the Defence Research and Development Organisation (DRDO), New Delhi.
She is widely celebrated as one of the key driving forces behind India’s indigenous development of Gallium Nitride (GaN) semiconductor technology—a critical component for strategic radar, electronic warfare, and next-generation military systems.
Early Life & Education
- Completed her studies in Electronics from the University of Delhi (South Campus) in 1988.
- Earned her Ph.D. from Jamia Millia Islamia, New Delhi, in 2005.
Career at DRDO
- Joined SSPL in 1989 as Scientist ‘B’. Over more than 35 years of service, she rose through the scientific ranks to Outstanding Scientist (Scientist ‘H’) in 2022.
- Appointed Director of SSPL on October 1, 2023, overseeing research across core strategic verticals including GaN/GaAs semiconductors, infrared sensors, terahertz devices, and quantum technology.
Pioneering GaN & Strategic MMIC Technology
- GaN MMIC Development: Served as Technology Director and Project Director for indigenous Gallium Nitride (GaN) and Gallium Arsenide (GaAs) Monolithic Microwave Integrated Circuits (MMICs).
- High-Frequency Systems: Led teams that engineered indigenous GaN MMICs operating up to X-band, as well as wideband C-to-Ku band Transmit/Receive (T/R) front-end chips essential for Active Electronically Scanned Array (AESA) radars, missile RF seekers, and electronic warfare suites.
- Strategic Self-Reliance: GaN-based power devices deliver substantially higher power density and thermal efficiency than traditional silicon. Because export controls tightly restrict GaN military chips globally, her team’s breakthroughs broke external dependencies and positioned India among the select few nations capable of fabricating these components domestically.
Key Awards & Recognition
- DRDO Outstanding Team Work Award (1999) for path-breaking research in GaAs-based MMIC technology.
- DRDO Path Breaking Research / Outstanding Technology Development Award (2016) for her foundational role in developing AlGaN/GaN High Electron Mobility Transistor (HEMT) technology.
- Author of over 120 publications in peer-reviewed national and international journals and conferences.
Through her leadership at SSPL, Dr. Mishra transitioned lab-scale semiconductor physics into mission-critical foundry fabrication, anchoring India’s push toward Atmanirbharta (self-reliance) in defense microelectronics.
What Is Gallium Nitride (GaN) Technology
Gallium Nitride, commonly known as GaN, is a semiconductor material used in high-frequency and high-power electronic systems.
It performs better than many traditional semiconductor materials because it can handle high voltages, high temperatures, and high frequencies. This makes it ideal for advanced defence systems that require powerful and reliable electronic performance.
Why GaN Is Important
GaN technology enables:
- Faster signal processing
- Higher power output
- Better energy efficiency
- Reduced size and weight of electronic systems
- Improved reliability in harsh operating environments
These advantages make GaN one of the most important technologies in modern defence electronics.
How Powerful Is India’s New GaN Chip
A single GaN chip measuring just 3.5 mm by 3 mm can deliver up to 30 watts of power. According to the Ministry of Defence, the chip can operate at speeds up to 300 times faster than silicon in specific applications. This capability significantly enhances India’s defence electronics ecosystem.
What is the Applications Of Indigenous GaN Technology
GaN technology is particularly useful for Active Electronically Scanned Array (AESA) radars. These radars use electronic beam steering instead of mechanical movement, allowing faster target detection and tracking. The technology improves radar performance while reducing system size and power consumption.
Electronic Warfare Systems
GaN components can generate, amplify, receive, and control high-frequency signals. This makes them highly valuable for electronic warfare equipment used to detect, disrupt, and respond to hostile electronic signals.
Communication Systems
The technology can also improve secure military communications. Its ability to operate efficiently at high frequencies enhances data transmission capabilities across defence networks.
India GaN Technology Breakthrough: Indigenous Manufacturing Capability Strengthened
The Solid State Physics Laboratory has developed indigenous processes for producing four-inch silicon carbide wafers. These wafers are critical for manufacturing advanced GaN-based semiconductor devices.
MMIC Production Capability Established
SSPL has successfully fabricated GaN High Electron Mobility Transistors (HEMTs). These devices have been rated up to 150 watts. Meanwhile, MMICs developed for X-band applications have achieved ratings up to 40 watts.
Limited production capacity for GaN-on-Silicon Carbide MMICs has already been established at the Gallium Arsenide Enabling Technology Centre in Hyderabad.
Where Will This Technology Be Used
The indigenous GaN technology can be integrated into:
- Fighter aircraft
- Naval warships
- Air defence systems
- Guided missiles
- Unmanned aerial vehicles (UAVs)
- Electronic warfare platforms
These applications will strengthen India’s military capabilities across all domains.
India GaN Technology Breakthrough: Use Beyond Defence
The technology also has civilian and strategic applications. Potential sectors include:
- Space technology
- Aerospace systems
- 5G communications
- Satellite communications
- High-performance electronics
Government Support And Industry Participation
The Innovations for Defence Excellence (iDEX) programme has actively supported indigenous semiconductor development. In December 2023, the Ministry of Defence signed a contract with Agnit Semiconductors Private Limited for the design and development of advanced GaN components.
These components are intended for next-generation wireless transmitters used in radars and electronic warfare systems. The initiative highlights the growing role of Indian startups in defence technology development.
Why India GaN Technology Breakthrough Matters For India
GaN technology is considered a strategic capability globally. Many countries restrict the export of advanced semiconductor technologies because of their military importance.
India previously depended heavily on imported GaN components. With indigenous development now achieved, India’s defence systems can become more secure and less vulnerable to foreign supply disruptions.
Boosting Defence Self-Reliance
The achievement supports the government’s Atmanirbhar Bharat vision. It strengthens domestic research, manufacturing capabilities, and future export potential in advanced defence technologies.
