ACT CHANNELIZER TUNER

THE DEVELOPMENT OF A NEW VHF/UHF CHANNELIZER TUNER ARCHITECTURE USING ACOUSTIC CHARGE TRANSPORT (ACT) TECHNOLOGY IS PROPOSED. THE TUNER TRANSLATES A 15 MHZ SPECTRAL BANDWIDTH IN THE VHF/UHF RANGE INTO A DIGITIZED OUPUT FOR DIGITAL SIGNAL PROCESSING. THE PROPOSED TUNER ARCHITECTURE IS UNIQUE COMPARED WITH CONVENTIONAL TUNER ARCHITECTURES, AND OFFERS THE POTENTIAL OF A VERY SMALL SIZE TUNER, PERHAPS AS A SINGLE HYBRID OR MONOLITHIC DEVICE. ALONG WITH SMALL SIZE, THE TUNER WILL ALSO BE VERY LIGHTWEIGHT, LOW COST, AND HAVE A LOW POWER CONSUMPTION. ANTICIPATED BENEFITS/POTENTIAL COMMERCIAL APPLICATIONS - THE VERY SMALL SIZE, LIGHTWEIGHT, LOW COST, AND LOW POWER CONSUMPTION OF THIS TUNER ARCHITECTURE WILL ALLOW SYSTEM CONCEPTS REQUIRING MULTIPLE TUNER CHANNELS ACROSS MULTIPLE ANTENNA ARRAY ELEMENTS FOR DIRECTION FINDING AND INTERFERENCE CANCELLATION, AS WELL AS MULTIPLE TUNER CHANNELS ACROSS AN ENTIRE FREQUENCY SPECTRUM TO PROVIDE VERY WIDEBAND SIGNAL INTERCEPT TO BE ECONOMICALLY PRACTICAL.
