Abstract
A 60 GHz high-efficiency HEMT MMIC chip set was developed including two fully-matched HEMT MMIC chips. A 2-mil thick MMIC with 300 mW output power and 22% efficiency and a 4-mil thick gain stage MMIC are described. They were used as building blocks of high power (1 to 50 watts) SSPA.Keywords
