Projected growth to $2.4 Billion by 2031

This report analyzes the GaN RF supply chain and technology trends from 2025 to 2031. The device market is projected to reach $2.4 billion by 2031.

• Telecom Infrastructure: having ~40% of the total GaN device market share in 2025, is expected to grow by ~11% in 2031. 5G continues to rollout in South-East Asia, base stations are being upgraded for efficiency improvement, 6G on the horizon by the end of the decade. GaN-on-SiC is still the dominant technology of choice.
• Mobile: GaAs dominates sub-7GHz band PAs for mobile. Given the current status of GaN-on-Si in high scale, it is unlikely that it hits the market as a competitor to GaAs in FR1 Handset PA.  However, GaN-on-Si can be attractive in bringing better power efficiency and potentially wider band operation as frequency goes beyond 10GHz, with the upcoming FR3 network deployment
• Defense: The defense GaN RF market is expected to grow by ~10% in 2031. Military radars and electronic warfare are primary growth drivers, with research into GaN-on-diamond substrates.
• SatCom: GaN devices, mainly used in ground-based VSAT systems, are gaining share from GaAs. Increased satellite launches may boost GaN RF adoption in LEO satellites.
  

 

U.S.–China Rivalry in RF GaN: Is EU falling behind?

As of 2026, the RF GaN supply chain remains centered on IDMs, supported by foundries, fabless players, and epiwafer suppliers, driven by stringent defense and high-power telecom requirements. The RF GaN device market in 2025 is concentrated, with SEDI, Qorvo, and MACOM accounting for nearly half of revenues. MACOM has licensed HRL’s 40-nm T3L GaN-on-SiC technology. In contrast, NXP plans to exit RF GaN and LDMOS amid weak telecom demand, while the announced Skyworks–Qorvo merger aims to create a major U.S. RF player and consolidate manufacturing capacity. China is rapidly localizing its GaN RF value chain under sanctions, led by domestic players such as SICC, Dynax, Sanan IC, etc., and expanding low-cost 6″ SiC wafer capacity despite ongoing geopolitical risks.

• In defense, GaN adoption is led by MACOM, Qorvo, Raytheon, Northrop Grumman, and CETC, with the U.S. DoD-trusted ecosystem remaining stable and additional players such as RFHIC and Winsemi expanding toward global defense markets.
• In telecom, Huawei, Ericsson, Nokia, ZTE, and Samsung dominate base-station deployments, with sanctions accelerating China’s domestic RF GaN supply chain. The shift toward higher-power, module-based 5G radios is increasing interest in cost-effective GaN-on-Si, intensifying competition with GaN-on-SiC, while the SiC wafer market remains concentrated and capacity expansion limited.

 

GaN-on-SiC Is Proven. GaN-on-Si Is Promising. Everything Else Is a Bet

GaN-on-SiC remains the preferred RF technology for 5G telecom and defense thanks to its high power density and superior thermal performance. The transition from 4" to 6" wafers continues but is progressing more slowly than expected. In parallel, GaN-on-Si device limited shipments for 5G base stations began in 2023, driven mainly by small-cell deployments and 8" production, with a potential move to 12" wafers in the early 2030s if telecom demand and 6G FR3 adoption materialize. GaN-on-SiC remains the most mature RF platform, while GaN-on-Si is gradually industrializing but must achieve stronger cost competitiveness. GaN-on-AlN and GaN-on-diamond remain in R&D, constrained by high cost, manufacturing complexity, and long qualification cycles.
