AGNIT Semiconductors: Building India’s Gallium-Nitride Chip Capability for Radar, Communications and Power Electronics

India’s semiconductor ambitions are expanding beyond conventional silicon chips. One Bengaluru deep-tech company is working in a particularly strategic part of this emerging ecosystem: gallium nitride, or GaN, semiconductors.

AGNIT Semiconductors, born from research at the Indian Institute of Science (IISc), is developing GaN semiconductor technology for high-frequency communications, strategic electronics and power applications. The company describes itself as a fab-lite GaN semiconductor company covering the technology chain from semiconductor wafers to components and modules.

This capability is important because GaN performs particularly well where conventional silicon begins to encounter limitations. Radar transmitters, advanced communication systems and compact power converters all demand high power, high frequencies and greater efficiency.

AGNIT is attempting to build these capabilities within India.

From IISc Research to an Indian Semiconductor Company

AGNIT has emerged from a long-running GaN research ecosystem at the Indian Institute of Science, Bengaluru.

IISc’s Centre for Nano Science and Engineering says AGNIT was founded by faculty members and alumni associated with CeNSE and the Department of Electronic Systems Engineering. The company has also been incubated at INCeNSE, the deep-technology business incubator housed at CeNSE.

The company’s technological foundations therefore go considerably deeper than simply designing a finished electronic product.

Its team has experience in semiconductor materials, device physics, fabrication, RF engineering and system development. AGNIT says its technology draws upon more than 18 years of expertise in GaN research, while its current portfolio spans wafers, semiconductor devices, circuit design and specialised device processing.

That materials-to-modules approach is particularly significant in the semiconductor industry.

India has traditionally possessed strong semiconductor design capabilities. Developing intellectual property across materials, fabrication processes and devices creates another layer of technological independence.

What Makes Gallium Nitride Different?

Silicon remains the foundation of modern electronics. However, it does not offer the best performance for every application.

Gallium nitride belongs to a group of materials known as wide-bandgap semiconductors. Its physical properties allow electronic devices to operate efficiently at high voltages, high temperatures and very high switching frequencies.

IISc researchers have highlighted GaN’s suitability for both high-power and high-frequency applications. GaN High Electron Mobility Transistors, or HEMTs, can switch rapidly, withstand high voltages and occupy less space than comparable conventional devices in many applications.

These characteristics can translate into electronic systems that are smaller and lighter while handling greater power.

For defence and aerospace equipment, this combination can be particularly valuable because size, weight and available electrical power are often tightly constrained.

From GaN Wafers to RF Devices

AGNIT is not restricting itself to a single semiconductor component.

The company’s present technology portfolio includes:

• GaN semiconductor wafers
• GaN RF devices
• evaluation boards
• semiconductor device processing
• circuit and module development

AGNIT describes its approach as taking GaN technology from “materials to modules.”

Developing capability across several stages of the semiconductor chain could allow devices to be customised for specific Indian requirements rather than depending entirely on imported components designed for global markets.

The company says it focuses on application-specific devices and on improving size, weight, power and cost, commonly abbreviated as SWaP-C.

GaN for Radar and Strategic Electronics

One of GaN’s most important applications lies in radio-frequency electronics.

Modern radar systems depend on semiconductor devices that can generate and amplify powerful radio-frequency signals efficiently. GaN devices can provide high power density while operating across demanding microwave frequency ranges.

This makes the technology relevant to applications such as:

AESA radars: Active electronically scanned array radars contain large numbers of transmit-receive modules. More efficient RF semiconductor devices can improve radar performance while reducing cooling and power requirements.

Electronic warfare systems: High-frequency transmitters are needed for jamming, electronic attack and several forms of spectrum operations.

Secure military communications: Compact and efficient RF amplifiers can support battlefield communications and high-capacity wireless links.

Space and aerospace systems: Satellites, aircraft and unmanned platforms place a premium on equipment with high performance and low weight.

IISc has specifically identified its GaN RF work as relevant to 5G communications and radar systems.

AGNIT similarly identifies strategic and telecommunications sectors among its principal markets.

Powering the Next Generation of Communications

GaN technology also has major potential in telecommunications.

Mobile base stations require RF power amplifiers to transmit signals over considerable distances. As networks move towards higher data rates and more complex frequency bands, the efficiency of these amplifiers becomes increasingly important.

AGNIT says GaN power amplifiers can provide high power density, improved efficiency, wider bandwidth and good linearity, helping reduce system complexity in wireless transmit applications.

The same underlying technology could support terrestrial communication networks as well as specialised wireless links.

Building such devices domestically would also expand India’s semiconductor value chain beyond assembling communications equipment from imported electronic components.

GaN and High-Efficiency Power Conversion

Another major opportunity lies outside radio-frequency electronics.

GaN transistors can switch electricity much faster than traditional silicon power devices. This allows power-conversion systems to use smaller passive components while reducing energy losses.

Potential applications include electric-vehicle chargers, telecom power supplies, data centres, industrial electronics and compact high-density power converters.

IISc’s GaN programme has already demonstrated devices and DC-DC converters intended to establish an indigenous materials-to-devices-to-systems technology platform. Researchers have also worked on technologies relevant to electric-vehicle battery chargers.

AGNIT lists power conversion alongside strategic electronics and telecommunications among the areas targeted by its GaN technology.

As electricity consumption rises in data centres, telecom networks and electrified transport, even relatively small improvements in conversion efficiency can become significant at scale.

Building the Semiconductor Beneath the System

AGNIT represents a different layer of the Make in India story.

India already manufactures or develops increasingly sophisticated radars, communication equipment, missiles, satellites, electric vehicles and industrial electronics. However, the critical semiconductor devices inside these systems can still originate from foreign supply chains.

Developing the underlying GaN wafer and transistor technology changes that equation.

Domestic semiconductor capability can provide greater control over device specifications, intellectual property, supply chains and future upgrades. This becomes especially important when components are intended for strategic systems.

The IISc ecosystem has also established the Gallium Nitride Ecosystem Enabling Centre and Incubator (GEECI), a low-volume semiconductor wafer and device production facility for GaN applications. IISc says the facility is intended to support commercially relevant devices including fast chargers and miniaturised power electronics.

Such research, prototyping and commercialisation infrastructure creates an important bridge between laboratory semiconductor breakthroughs and deployable Indian products.

An Indigenous GaN Technology Stack

AGNIT’s larger significance therefore lies in the breadth of the capability being developed.

Instead of working only on the circuit surrounding an imported transistor, the company is building expertise beginning with the semiconductor material itself.

Its chain extends through:

GaN material → wafer → semiconductor device → RF circuit → module → end system

This creates opportunities to retain more engineering knowledge and intellectual property within India.

AGNIT currently reports more than 20 patents associated with its GaN technology portfolio. It also highlights a multidisciplinary team with experience spanning academia, industry and government laboratories.

The company is therefore part of a wider shift in India’s technology ecosystem. Indian startups are increasingly attempting to commercialise technologies that previously remained confined to research laboratories.

From Laboratory Breakthrough to Strategic Manufacturing

Gallium nitride will not replace silicon across the semiconductor industry. Nor does it need to.

Its strength lies in applications where high power, high frequency, efficiency and compact dimensions become critical.

Those requirements appear repeatedly in radar, electronic warfare, telecommunications, satellites, electric vehicles, industrial power systems and data-centre infrastructure.

AGNIT Semiconductors is positioning itself within precisely this technological space.

Its roots in IISc’s GaN research programme provide a foundation in semiconductor materials and device engineering. Its commercial challenge is now to convert that research capability into reliable products manufactured at meaningful scale.

If that transition succeeds, AGNIT could contribute something more fundamental than another Indian electronic product. It could help establish an indigenous gallium-nitride semiconductor technology stack, providing Indian engineers with home-grown building blocks for some of the country’s most advanced electronic systems.

That is where AGNIT fits into the evolving Make in India semiconductor story: moving India from designing systems around imported chips towards designing and building the strategic semiconductor devices inside them.
