There is a need for high-speed digital signal processing anddetection techniques to downconvert and process Ka, Ku, X and S-Bandsignals. A GaAs integrated circuit version of a sampling mixer will beinvestigated for this purpose. A circuit configuration will be definedfor S and X-Band chips and specifications necessary for the developmentof the chip during a follow-on phase will be defined. Circuitimplications and design options for extending the work to Ku and Ka Bandregions will be studied.A GaAs MMIC sampling mixer will find applications in commercialcommunication circuits such as GPS receivers, cellular telephones, andwireless LAN.GaAs, MMIC, sampling, mixerSTATUS: Phase I Only
