Fast Tuning, Analog Notch Filters

In this program, we will develop a concept for microsecond tuning notches meeting the notch depth and insertion loss requirements of the application. We will define a full set of target specifications for the tunable notches that meet a current or future operational need. We will demonstrate through simulation that this technology can be used for microsecond tunable narrowband notch filters with minimal insertion loss. We will then design and optimize a resonator to minimize the size, maximize the Q (hence minimizing passband loss) and the tuning range, and optimize the precision in Phase II. We will then outline the technical risks for Phase II. Successful completion of this effort will form a solid foundation for building and testing a prototype tunable filter in Phase II.
