Abstract:

Digital-RF technology is a disruptive technological innovation capable of changing wireless communications, radar, and surveillance system architectures dramatically. Practical results have been achieved in proving that superconductor Digital-RF technology can be applied to such systems altering the way these systems have been traditionally built. In these systems, fundamental advantages of superconductivity translate into system benefits through enabling direct digital processing of wide band, high radio frequency (RF) signals and expanding digital domain throughout the entire system. The availability of relatively small 4K cryocoolers has lowered the foremost market barrier for cryogenically-cooled digital electronic systems. Recently major breakthroughs have been achieved in the development, demonstration, and successful delivery of the cryocooled superconductor Digital-RF receivers directly digitizing signals in a broad range from kilohertz to gigaherts. The demonstrat ed cryocooled Digital-RF systems are the world.s first and fastest directly digitizing receivers operating with live satellite signals in X-band and performing signal acquisition from HF to L-band with ~30 GHz clock frequencies. Digital-RF approach can also be extended to transmitters and expand digital domain into power amplifiers by utilizing switched amplifiers.

Biography:

Dr. Oleg Mukhanov, Senior Vice President and General Manager, joined HYPRES, Inc. in April 1991 as a Superconductive Integrated Circuit Designer to initiate the development of digital circuits based on Rapid Single Flux Quantum (RSFQ) logic family. He is currently responsible for coordination of all technical areas: circuit design, test, fabrication, cryopackaging, and system integration. Dr. Mukhanov has initiated and been involved in multiplicity of HYPRES projects including development of high-performance superconductor A/D, D/A, and T/D converters, DSP circuits, RAM for a variety of applications including communications, radar, EW, and instrumentation. Dr. Mukhanov is a co-inventor of the RSFQ logic and was the designer of a number of the world.s fastest digital circuits. Dr. Mukhanov is a Senior Member of the IEEE, authored over seventy scientific papers and several patents. He was member of many organizing and program committees of national and international supercondu ctor electronics conferences. Dr. Mukhanov is board member of the Applied Superconductivity Conference, member of Council on Superconductivity, and editor of IEEE Transactions of Applied Superconductivity. He was a President of the US Committee for Superconductor Electronics in 2005-2007. He received his Ph.D. in Physics (1987) from Moscow State University and M.S. in Electrical Engineering (1983) from Moscow Engineering Physics Institute.
