3 Nitride (GaN) high-electron-mobility transistors (HEMTs) have been widely used for cellular base stations and other high-power and high-frequency applications owing to their superior material properties. This paper describes the features and characteristics of the world s first commercialized GaN HEMTs. Specifically, it introduces our 400W gan hemt Doherty amplifier for cellular base stations and 20W broad band gan hemt for fixed wireless communications. For satellite communications and weather radars, we have also developed a high-power and high-reliability gan hemt .

4 These GaN HEMTs contribute to the creation of small-form-factor, light-weight, and power-efficient transmitters for wireless communication. gan hemt gan hemt gan hemt for Wireless Communication Seigo Sano Kaname Ebihara Takashi Yamamoto Tomio Satoh Naoyuki Miyazawa 1 70 gan hemt Johnson GaN Si 27 GaAs 15 GaN 2 1 GaN 2 2 gan hemt 3 gan hemt GaN AlGaN 2 GaN
