Not Available Alameda Applied Sciences Corporation (AASC) proposes to develop a new type of RF and millimeter wave amplifier based on pulse compression. The amplifier is based on the use of a diamond membrane that is turned from an insulating state (thus transmitting RF) to a conducting state (thus reflecting RF) when irradiated by ultraviolet (UV) radiation. Such a RF amplifier is an enabling technology for a whole class of high power RF and millimeter wave devices that would otherwise be impractical. The Phase I to demonstrate the feasibility of the concept. A chemical vapor deposition diamond window will be irradiated with UV radiation from a laser (4th harmonic Nd:YAG) and reflection of microwave power from the window will be demonstrated. The UV power required for practical devices will be determined. The Phase II effort will develop a RF amplifier using the pulse compression technique. The diamond switch will be coupled to a high power microwave source such as the phigtron, developed at the University of Maryland. The Phase III will be an aggressive commercialization campaign aimed at the several military and civilian uses of high power RF.
