Potential NASA Commercial Applications: 1. In flight reconfigurable SDR agnostic RF front end for current and future RF communications and radar EFA, SDST, STDN, SGLS, TDRSS, Lunar Crew Communications, CEV, networked, surface/harsh environment, etc. 2. DOD software defined radio (JTRS, AMF, etc), terrestrial, airborne, naval, Electronic Warfare, C41SR 3. Wideband operation and low power are ideal for cognitive and mobile adaptive ad hoc networked (MANET) communications (802.XX) AS WELL AS TRIDITIONAL COMMERCIAL WIRELESS (GSM/EDGE, CDMA, UMTS-WCDMA, etc) 4. Homeland Security and Emergency inter-network access with a single mobile radio 5. This technology is also feasible for radar, and in particular, in collision avoidance automotive applications. Here the six port is configured as a reflectometer that establishes amplitude and phase relations between RF signals. Using a patch antenna at Ka-band frequencies, the sensor module volume would not exceed 3 cubic inches. Maximum range would be about 20 feet with 2% accuracy.
