Abstract:

GROWTH OF SOPHISTICATED MILLIMETER-WAVE (MMW) SATELLITE COMMUNICATIONS (SATCOM) IS DRIVING DESIGN OF SATELLITE GROUND TERMINALS TOWARD HIGHER FREQUENCY, LOWER COST, HIGHERRELIABILITY, REMOTE OPERATION, FEWER MAINTENANCE ACTIVITIES,AND FREEDOM FROM EMI/EMP. THE MMW SATCOM SYSTEMS REQUIRE A WIDE IF BANDWIDTH, EITHER TO ACCOMODATE HIGH DATA RATES OR TO PROVIDE FOR JAM-RESISTANCE THROUGH USE OF WIDEBAND FREQUENCY HOPPING AND/OR SPREAD SPECTRUM TECHNIQUES. BOTH RECTANGULAR WAVEGUIDE AND COAXIAL CABLE LINKS SUFFER DISADVANTAGES OF INFLEXIBILITY, HIGH LOSS, HIGH COST, DELAY DISTORTION, EMI/EMP PROBLEMS, AND PHASE DISTORTIONS. OVERCOMING THESE SHORTCOMINGS MAY BE POSSIBLE THROUGH EXPLOITING THE CHARACTERISTICS OF RECENTLY DEVELOPED ELECTRO-OPTICAL MODULATORS AND DETECTORS AND WIDE-BAND- WIDTH, LOW-LOSS FIBER-OPTIC CABLE. THIS PROJECT INVESTIGATES AND DESIGNS 20 AND 30 GHZ FIBER-OPTIC LINKS USING EXTERNAL ELECTRO-OPTIC MODULATORS AND MESFET (OR SCHOTTKY DIODE) PHOTODETECTION FOR SATCOM DOWN AND UP LINK. A WIDEBAND MICROWAVE FIBER-OPTIC LINK USING DIRECTLY MODULATED LASER DIODE IS DESIGNED FOR TERMINAL IF APPLICATION. FURTHERMORE, THE PROJECT INVESTIGATES A 30/20 GHZ INTEGRATED TERMINAL CONCEPT CONFIGURED TO REALIZE THE PROMISED IMPROVEMENTS IN COST EFFECTIVENESS AND PERFORMANCE OF ELECTRO-OPTIC AND FIBER-OPTIC DEVICES.
