Passive Superconducting Microwave Circuits for 2-20 GHz Bandwidth Analog Signal Processing

A new technology for making analog signal-processing devices such as linear-FM chirp filters with time-bandwidth products up to 1000 is being developed using niobium stripline on sapphire. Preliminary results of delay lines, resonators, and a 25-ns, 2-GHz chirp filter will be presented.
