THE OBJECTIVE OF PHASE I STUDY IS TO CONDUCT A MILLIMETER- WAVE (MMW) SYSTEM SURVEY (INCLUDING STACOM, RADAR, SECURITY COMMUNICATIONS, RADIOMETER, SEEKER, DESIGNATOR, SPACE COMM, AND ECM SYSTEMS) TO IDENTIFY SEMICONDUCTOR DEVICES/ COMPONENTS

THE OBJECTIVE OF PHASE I STUDY IS TO CONDUCT A MILLIMETER- WAVE (MMW) SYSTEM SURVEY (INCLUDING STACOM, RADAR, SECURITY COMMUNICATIONS, RADIOMETER, SEEKER, DESIGNATOR, SPACE COMM, AND ECM SYSTEMS) TO IDENTIFY SEMICONDUCTOR DEVICES/ COMPONENTS REQUIREMENTS, CRITICAL PROBLEMS AND SYSTEM SPECIFICATIONS. KEY MMW TECHNOLOGIES SUCH AS PHASED/ ADAPTIVE ARRAY, ACTIVE ARRAY, FAST-HOPPING FREQUENCY SYNTHESIZER, ARE IMPORTANT FOR THE FUTURE NAVAL EHF SYSTEMS,AND WILL BE INVESTIGATED AND FORCASTED. SI, GAAS, INP AND OTHER III-V MATERIALS, DEVICES, AND MONOLITHIC IC'S ARE CONSIDERED FOR LOW NOISE AND POWER APPLICATIONS. EXOTIC DEVICES SUCH AS PREMEABLE BASE TRANSISTOR AND VERTICAL MESFET MAY PROVIDE HIGH POWER, HIGH FREQUENCY POTENTIALS. NEW POWER COMBINING TECHNIQUE USING AN ACTIVE ANTENNA REFLECTOR MAY RESULT IN HIGH POWER AND HIGH EFFICIENCY MMW SYSTEMS APPLICATIONS, TECHNOLOGY TRENDS, THE FUTURE R&D NEEDS/PRIORITY AND R&D TOPICS/TASK/COST WILL BE DISCUSSED AND RECOMMENDED AS A RESULT OF THIS SURVEY.
