Gallium Nitride Sector: Growth Drivers and Challenges

Growth Drivers 

• EV and power conversion demand: The demand for EV fast charging and onboard power conversion is one of the top growth drivers in the gallium nitride market. In April 2024, Infineon Technologies produced the world’s first 300mm GaN power wafer, increasing chip yield and reducing per-unit cost by 2.3x. The innovation enables the scalable production of EV chargers, renewables, and data center equipment. As EV penetration increases, GaN’s ability to reduce losses and increase efficiency leads to its replacing silicon in the mobility infrastructure. Now, automakers are trialing GaN-based traction inverters in next-generation electric platforms slated for 2026 release.
   
• 5G and telecom infrastructure expansion: The rapid expansion of 5G and telecom infrastructure demands high-frequency GaN RF devices. The U.S. FCC revised emission certifications for GaN RF applications in 5G and satellite communications in March 2024. These updates ensure that telecom vendors can operate without interference and receive faster approval. At the same time, Europe introduced compliance standards via ETSI. As network densification continues, GaN provides better bandwidth, more power, and less heat dissipation. GaN transistors are being integrated by global telecom operators in base station rollouts over dense urban zones.
   
• Power electronics and sustainability mandates: The rise of GaN in power electronics is also fueled by sustainability mandates. At COP28 in February 2024, nearly 200 countries pledged to double energy efficiency by 2030, with GaN highlighting energy-saving technologies. In March 2024, Efficient Power Conversion introduced the EPC9178 reference design for photovoltaic optimizers to increase rooftop solar efficiency. These developments fit in with global decarbonization agendas and reinforce GaN’s place in the energy transformation. GaN is enabling emerging economies to leapfrog legacy infrastructure and leap directly into efficient electrification.

GaN in Aerospace and Satellite Communications

The high power efficiency and thermal stability of Gallium Nitride (GaN) contribute to a revolution in aerospace. In particular, these characteristics are critical for satellite communications and advanced radar systems. Having recognized this potential, the U.S. Department of Defense (DoD) set aside a sizable USD 1.7 billion in 2024 to develop and deploy GaN in radars and missile defense systems to boost signal clarity and extend operational range. In addition to this, the growing number of Low Earth Orbit (LEO) satellite constellations, which are expected to reach more than 50,000 units by 2030, as per Euroconsult, further underscores the growing importance of GaN. GaN RF amplifiers are a crucial part of these LEO satellites, which require these devices to transmit data at high frequencies. The demand for GaN technology in satellite systems is being pushed by major players in the aerospace industry like SpaceX and OneWeb. GaN is attractive for satellites since it can reduce weight by 30% and increase efficiency by 50% over traditional silicon-based systems.

GaN in Medical Imaging and Portable Healthcare Devices

High-efficiency power solutions for medical imaging systems and portable diagnostics are being revolutionized by Gallium Nitride. The FDA’s 2023 guidelines recognize this potential, and as a result, energy-efficient medical devices are being mandated for the adoption of GaN-based MRI machines and X-ray systems. GE Healthcare has noted that these advanced systems provide a 35 percent reduction in power consumption. Additionally, portable ultrasound devices with GaN chips are showing significant boosts, being 40 percent lighter and 20 percent faster in imaging speed, which is key for remote care, the WHO says. The growing adoption of telemedicine is driving the robust growth of the healthcare gallium nitride market, which is expected to grow at a 28% CAGR between 2025 and 2037. Startups such as Butterfly Network are also taking advantage of GaN to create miniaturized imaging tools that show the power of this technology. At the same time, the NIH has pledged USD 250M in funding in 2024 to develop GaN-enabled wearables for chronic disease monitoring, indicating increasing awareness of GaN’s promise in healthcare.

Challenges

• Vulnerabilities of the raw material supply chain: Raw material supply chain vulnerabilities remain a key challenge. In 2023, the restriction of gallium exports from China, a critical ingredient for GaN semiconductors, disrupted the global production of these semiconductors. This led to higher prices and diversification in sourcing. As a result, the U.S., Japan, and the EU launched domestic mining and refining initiatives. However, the pressure remains on midstream manufacturers that use gallium inputs from China in the short term. To diversify gallium procurement, several producers have begun sourcing from Africa and Latin America.
   
• Shortage of skilled talent: Another challenge is the lack of skilled talent for GaN design and fabrication. To bridge this gap, in April 2024, India’s MeitY launched workforce development for GaN manufacturing. In North America, DOE funding exists, but the lack of experienced engineers in wide bandgap semiconductors constrains the pace of scaling. In the absence of coordinated talent pipeline programs, this bottleneck may delay commercialization across some verticals. There are specialized certification programs being developed by universities to train GaN-specific engineering talent.
