ABSTRACT: Auriga will produce an ultra-linear high-power, high-efficiency amplifier to be used in satellite communication systems. The innovative approaches are proposed and validated in Phase I. The enabling technology is Gallium Nitride (GaN) ,which is well-known for its power handling capability. State-of-the-art 0.15 m gate GaN HEMT technology will be used in the design. The concept will be verified by device characterization, modeling and a prototype amplifier demonstration. MMIC amplifiers will be the final goal and will be fabricated in Phase II. Also, a proof-of-concept high-linear and high-power amplifier will be demonstrated in Phase I. Auriga will also evaluate the impact of radiation hardness for GaN HEMTs device in Phase I. BENEFIT: The successful outcome of the project will provide high-efficiency linear high-power amplifiers for use in satellite communications systems. The amplifier design methodology developed under this effort can be used in a broad range of military and commercial communications applications.
