AEROMET PROPOSES TO DEVELOP A SENSOR SYSTEM FOR THE PURPOSE OF MONITORING RF FIELD STRENGTH ENERGY. PHASE I WILL CONCENTRATE ON THE DESIGN AND DEVELOPMENT OF A UNIQUE PROGRAMMABLE SENSOR THAT CAN SENSE THE ENERGY IN VARIOUS FREQUENCY BANDS. THE SENSOR WILL ACT AS A STAND ALONE UNIT AND BE POWERED BY SOLAR CHARGED BATTERIES. THE SENSOR WILL BE DESIGNED SO THAT MANY OF THEM CAN BE OPERATED IN CONJUN ...

NOISE PARAMETER MEASUREMENTS OF MICROWAVE TRANSISTORS AND MMICS ARE BEST PERFORMED WITH ON-WAFER, PROBE SYSTEMS. TWO KEY PARAMETERS OF THESE SYSTEMS IS THE LOSS FROM THE INPUT TUNER TO THE DEVICE UNDER TEST (DUT), AND FROM THE DUT TO THE RECEIVER; THIS IS TYPICALLY DOMINATED BY THE WAFER PROBE. THIS PHASE I WORK WILL DEMONSTRATE A WAFER PROBE PROTOYPE WITH SIGNIFICANTLY LOWER LOSS THAN CURRENTLY A ...

FOR FAST RISE TIME PULSES AND HIGH POWER MICROWAVE APPLICATIONS, A NEW CLASS OF VARISTOR DEVICES IS NEEDED THAT SURPASSES THE PERFORMANCE OF PRESENT DEVICES. CURRENTLY AVAILABLE VARISTOR MATERIALS DEPEND ON SEMICONDUCTOR JUNCTIONS, AVALANCHE MECHANISMS, OR ZENER ACTION, OR A COMBINATION OF THESE EFFECTS. AN ALTERNATIVE THAT OFFERS SIGNIFICANT ADVANTAGES IN TERMS OF RESPONSE CHARACTERISTICS, RELIAB ...
