Advanced device technologies for defense systems

The performance requirements of defense systems to detect small signals in the presence of clutter or large interferers, to see further than the adversary, and discriminate between targets in a complex environment, has driven the need for ever more capable device technologies for focal plane arrays (FPAs) and monolithic microwave integrated circuits (MMICs). This paper discusses the history, and current state, of several key technologies developed at Raytheon to enable our systems to meet mission needs. The technologies include Gallium Nitride (GaN) MMICs and Mercury Cadmium Telluride (MCT) Infrared Focal Plane Arrays (FPAs). Emerging technologies for heterogeneous integration and Short Wave Infrared (SWIR) FPAs are also discussed.
