Abstract

Record performance at 4GHz has been obtained by using field plated AIGaN/GaN HEMTs. For devices on sapphire substrate, high power density (12W/mm) as well as high efficiency (58%) have been measured. Devices on Sic substrate yielded power density up to I8.8W/mm and efficiency up to 74% (with 6Whm). Excellent linearity performance was also achieved: while maintaining a carrier to third-order intermodulation ratio of 30dBc device yielded 2.4W/mm with 53% PAE.
