Abstract

A high efficiency 1.4 W MMIC power in the K-Band frequency band has been developed. A process technology optimized for high efficiency performance and an accurate design technique allowed us to achieve a power added efficiency of 42% with good noise power ratio figure. These performance make this device suitable for K-Band commercial satellite systems as part of antenna element array.
