Development of a Novel Efficient Solid State Compact RF/microwave DEW System

Aria Microwave System Inc. (AMS) will develop a lightweight, compact, scalable DEW system with 60% - 90% DC-to-RF efficiency. Examples of an S-Band concept system show that lethality levels > 1 W/cm ^2 at 100 meters can be attained with DC power in 10’s of kW, 10% duty cycle. The system uses AMS’s proprietary solid state, compact, lightweight, high efficiency, high power, active cavity amplifier (ACA), in conjunction with a 1m x 1m antenna array. The small size and lightweight of the ACA permit each array element to be individually driven by an amplifier, with its amplitude and phase controlled at its preamplifier. Rapid electronic scan, multiple beam, target locking, and beam shaping etc. are attainable for a myriad of operational requirements. Basic principles of the ACA-array approach can be applied from low UHF to high microwave frequencies. Main effort of Phase I will be to develop a conceptual design of a full power S-Band demonstration system, to be constructed during Phase II. Phase I activities will also involve interactions with other defense contractors as potential collaborators
