Fast Tuning, Analog Notch Filters

In this program, we will develop a concept for microsecond tuning 3 MHz BW HTS bandpass filters meeting the sharp rejection and insertion loss requirements of the application. We will define a full set of target specifications for the tunable bandpass filters that meet a current or future operational need. We will perform at least two design/fabricate/test cycles. At the end of the first year, we will perform a laboratory demonstration of the tunable bandpass filter. In the second year, we will focus on improved the power handling capability of the tunable filter. At the end of the second year, we will perform a laboratory demonstration of a filter meeting all of the specifications of the application. In the Phase II option, we will build a laboratory prototype to demonstrate the advantages of this technology. Successful completion of this effort will form a solid foundation for building and testing a fieldable prototype in Phase III.
