DEVELOPMENT OF NITRIDE-BASED TECHNOLOGY FOR SPACE: ENABLING NEW FRONTIERS

Thomas Jenkins; Scott Sheppard; William L. Pribble; D. Emerson; Zoltan Ring; Richard Peter Smith

Gallium nitride based microwave technology is being developed in an Air Force Dual-Use Science and Technology project. The technology has previously demonstrated significant characteristics for high power operation and robustness in extreme environments. Its desirable features (such as high breakdown voltage), overall development issues, and systems implications are reviewed. In this context, the programs recent advancements in state-of-the-art performance are presented, such as 14.8 W pulsed at 10 GHz with a 6mm HEMT with 27% PAE and 11.7 dB gain.
