HEMT market seen reaching $5.6 billion by 2030

The Business Research Company says the high electron mobility transistor market will grow from $3.29 billion in 2025 to $3.65 billion in 2026, then climb to $5.6 billion by 2030. Demand is being driven by 5G, defense, aerospace and satellite broadband, with North America leading in 2025 and Asia-Pacific expected to grow fastest.

Why it matters: - High electron mobility transistors sit at the center of high-frequency wireless, radar and satellite systems. - The market’s forecast growth points to rising demand for faster, more efficient semiconductor devices as telecom and defense networks advance. - Wider use of 6G, mmWave and satellite broadband could expand the role of HEMT devices in next-generation infrastructure.

What happened: - The Business Research Company published its High Electron Mobility Transistor Market Report 2026, covering market size, trends and a global forecast through 2035. - The report puts the HEMT market at $3.29 billion in 2025 and projects $3.65 billion in 2026. - The report forecasts the market will reach $5.6 billion by 2030, implying a 11.3% CAGR during the forecast period. - North America held the largest market share in 2025. - Asia-Pacific is forecast to be the fastest-growing regional market in the coming years.

The details: - Historical growth was driven by 4G and early 5G telecom infrastructure, broader use of gallium arsenide-based RF devices, defense radar and surveillance upgrades, higher telecom base-station investment and smaller RF and microwave components. - Future growth is expected to come from 6G development, mmWave spectrum use, wider adoption of gallium nitride and silicon carbide HEMT devices, satellite broadband growth including low Earth orbit constellations, and demand for energy-efficient RF power amplification. - The forecast period is also expected to see more HEMT use in aerospace and space communications. - Anticipated product trends include GaN HEMT adoption for high-frequency RF and microwave applications, integration of mmWave and microwave communication systems, greater use in satellite payload amplifiers, and more radar and electronic warfare applications. - The report highlights a push for higher power density and better thermal efficiency in RF power amplifiers. - A high electron mobility transistor uses a heterojunction interface to achieve higher electron mobility than traditional transistors. - That design supports faster switching, higher-frequency operation and stronger performance in RF and microwave applications. - HEMTs are used in communication systems and high-speed electronic circuits to improve signal amplification and operational efficiency. - Rising demand for high-frequency electronics is a key market driver. - High-frequency electronics are components designed to operate at gigahertz-level frequencies for wireless communication, radar and satellite uses. - The rapid rollout of 5G networks, especially in developed countries, is increasing demand for HEMT devices. - In Australia, about 37% of mobile network sites had 5G by January 2023, up from 28% in January 2022, according to the Australian Communications and Media Authority in December 2024. - The report also includes market attractiveness scoring, TAM analysis, company scoring matrix graphics and tables, Excel-based forecasting dashboards, market hotspot infographics, and updated graphics and tables.

Between the lines: - The forecast suggests HEMT growth is shifting from legacy telecom upgrades toward newer power-hungry applications in 6G, satellite broadband and electronic warfare. - North America’s current lead and Asia-Pacific’s expected acceleration point to a market split between established demand and faster infrastructure buildout. - The emphasis on GaN and SiC signals a broader move toward materials that can handle higher power and heat in advanced RF systems.

What's next: - The company is offering a free sample report and the full market report online. - Industry demand will likely track 6G planning, mmWave deployment, satellite broadband launches and continued 5G expansion. - The report’s regional outlook suggests future growth will depend heavily on telecom investment in Asia-Pacific.
