Indian Defence Technology: Indigenous Systems, GaN MMIC and Radar

Profile & Intelligence Breakdown

Executive Overview

India's defence technology ecosystem is accelerating its transition from licensed assembly to sovereign, indigenous design of critical electronic subsystems, advanced materials, and radar technologies.

A major milestone in September 2026 is the breakthrough deployment of indigenous Gallium Nitride (GaN) Monolithic Microwave Integrated Circuit (MMIC) technology developed by DRDO and domestic research partners.

Why Gallium Nitride (GaN) MMIC is a Game Changer

Compared to legacy Silicon or Gallium Arsenide (GaAs) semiconductors:

• Higher Power Density: Enables significantly smaller, lighter, and more powerful RF amplifiers.
• Thermal Efficiency: Operates at higher temperatures without catastrophic breakdown.
• Radar Performance: Forms the core transceiver modules of modern Active Electronically Scanned Array (AESA) radars for fighter jets (Tejas Mk1A/Mk2), warships, and missile guidance systems.

Indigenous Defence Capabilities Spectrum

1. Electronic Warfare (EW) Suites: Indigenous jamming and signal intelligence systems (e.g., Himshakti, Samyukta).
2. Sensor & Electro-Optics: Thermal imagers, laser designators, and multi-spectral infrared search-and-track (IRST) pods.
3. Advanced Composites & Metallurgy: High-temperature alloys for jet engines and radar-absorbing stealth coatings.
