✦ Synopsis

Delay-line microwave filters using high temperature superconductors are reviewed. First, a design procedure for delay-line filters based on an inverse scattering algorithm is described. The algorithm allows for the decay of the amplitude of the wave in the delay line. Furthermore, frequency-dependent losses and dispersion as well as multiple transits of the wave between taps are allowed for. Devices to be reviewed are linear phase and quadratic phase (chirp) filters, while an example of use in a system is a cueing receiver which identifies regions in the frequency spectrum for further analysis.
