According to our (Global Info Research) latest study, the global GaN on SiC Epitaxy (Epi) Wafers market size was valued at US$ 245 million in 2025 and is forecast to a readjusted size of US$ 735 million by 2032 with a CAGR of 17.2% during review period.
Gallium nitride (GaN) transistors and integrated circuits (ICs) offer fundamental advantages over silicon. GaN-based solutions exceed the performance capabilities of silicon in speed, temperature, and power handling. These improvements offer greater efficiency, significantly reduced size and weight, reduced cost, and improved thermal performance.
Currently the key size is 4 inch SiC Epitaxial Wafer. In next few years, the 6 inch SiC Epitaxial Wafer will grow faster. Now Wolfspeed, Inc is the leader of GaN-on-SiC HEMT Epitaxial wafer in the world.
The GaN RF Devices include Power Amplifier PA, Low Noise Amplifier LNA, RF Switch, etc. Gallium nitride (GaN) technology continues to evolve, pushing the limits of what’s possible with ever-increasing power density, reliability and gain in a reduced size. No longer a technology just for defense/aerospace applications, GaN is enabling higher and higher frequencies in more complex applications, such as phased arrays, radar, base transceiver stations for 5G, cable TV (CATV), VSAT and defense communications. At present, GaN RF devices are mainly dominated by several companies such as Sumitomo Electric Device Innovations (SEDI), Wolfspeed, Qorvo and NXP.
