THE OBJECTIVE OF THE PHASE I RESEARCH IS TO STUDY THE DEVELOPMENT OF VARIOUS TYPES OF LOW NOISE 44GHZ RECEIVER FRONT ENDS, AND TO IDENTIFY DEVELOPMENTAL DIFFICULTIES AND TECHNICAL RISKS ASSOCIATED WITH EACH DESIGN.

THE OBJECTIVE OF THE PHASE I RESEARCH IS TO STUDY THE DEVELOPMENT OF VARIOUS TYPES OF LOW NOISE 44GHZ RECEIVER FRONT ENDS, AND TO IDENTIFY DEVELOPMENTAL DIFFICULTIES AND TECHNICAL RISKS ASSOCIATED WITH EACH DESIGN. A HIGHLY RELIABLE, SPACE QUANTIFIABLE, LOW NOISE 44GHZ IS RECEIVER NEEDED. THE STUDY WILL ESTABLISH THE OPTIMUM COURSE TOWARD THE DEVELOPMENT OF THE DESIRED RECEIVER. ONE PRINCIPAL OUTPUT OF THE EFFORT WILL BE THE IDENTIFICATION OF NOVEL APPROACHES TO LOW NOISE RECEPTION AT 44 GHZ. NEW AND ADVANTAGEOUS METHODS OF MIXER CONSTRUCTION AND FABRICATION WILL BE DESCRIBED. AT THIS TIME IT APPEARS THAT AN IMAGE REJECT TYPE MIXER CAN BE DEVELOPED WITH A SSB NOISE FIGURE LESS THAN 4.5 DB. PRACTICAL AND THEORETICAL CONSIDERATIONS WILL BE MADE IN ESTABLISHING THE RELATIVE PERFORMANCE POTENTIAL OF BOTH FET AND RF AMPLIFIER FRONT ENDS AND LOW NOISE DOWN CONVERTERS. THE COMPARISON WILL RESULT IN A DECISION AS TO THE BETTER APPROACH.
