Abstract
A NOVEL, ADVANCED, MONOLITHIC GAAS RF SWITCH MATRIX FOR SATELLITE COMMUNICATIONS APPLICATIONS USING A DESIGN CONCEPT ORIGINALLY DEVELOPED FOR A MONOLITHIC GAAS IF SWITCH MATRIX WILL BE STUDIED FOR APPLICATION TO RF SWITCHING APPLICATIONS. PRELIMINARY ESTIMATED RF SWITCH MATRIX PARAMETERS INDICATE THAT ATTRACTIVE PERFORMANCE FOR LARGE ARRAYS APPEARS FEASIBLE AT 20 GHZ, ENCOURAGING FURTHER VERIFICATION FOLLOWED BY IMPLEMENTATION. IN THIS APPROACH, PASSIVE FET SWITCHES ARE USED FOR SIGNAL STEERING, WHILE FET BUFFER AMPLIFIERS PROVIDE AN OVERALL INSERTION LOSS OF 0 DB, ALLOWING TWO DIMENSIONAL CASCADING TO FORM VERY LARGE ARRAYS (PERHAPS UP TO 100 X 100), ALSO WITH 0 DB INSERTION LOSS. A PROPRIETARY PACKAGING CONCEPT WILL ALSO BE INVESTIGATED DURING PHASE I TO FACILITATE THE MODULAR CONSTRUCTION OF LARGE CROSSPOINT MATRICES AND THE INTERFACE OF THE MONOLITHIC IF SWITCH MATRIX TO OTHER SYSTEMS COMPONENTS. PHASE II WILL CONCENTRATE ON DEMONSTRATION OF THE MONOLITHIC RF SWITCH MATRIX CONCEPT BY FABRICATION OF A 3 X 3 MATRIX AND DESIGN OF A 10 X 10 (OR TBD SIZE) SWITCH MATRIX. THE ULTIMATE GOALS OF THIS PROGRAM WILL BE A SPACE QUALIFIABLE RF SWITCH MATRIX TECHNOLOGY FOR ADVANCED SATELLITE COMMUNICATIONS SYSTEMS, SIGNIFICANTLY ENHANCING COMMUNICATIONS CAPABILITIES WHILE SIMULTANEOUSLY REDUCING SATELLITE COMPLEXITY.
