The possibility of controlling the bandwidth and the dispersion of a tunable magnetostatic volume wave (MSVW) delay line filter based on yttriumm-iron-garnet (YIG) films is demonstrated. The simulation has been performed on a MSW filter consisting of two delay lines in cascade having opposite dispersion properties: a backward volume wave delay line and a forward volume wave one. The filter can be used effectively in the microwave frequency range for bandwidths between 20 MHz and 200 MHz, with the center frequency tunable with the DC magnetic bias.

Abstract
The possibility of controlling the bandwidth and the dispersion of a tunable magnetostatic volume wave (MSVW) delay line filter based on yttriumm-iron-garnet (YIG) films is demonstrated. The simulation has been performed on a MSW filter consisting of two delay lines in cascade having opposite dispersion properties: a backward volume wave delay line and a forward volume wave one. The filter can be used effectively in the microwave frequency range for bandwidths between 20 MHz and 200 MHz, with the center frequency tunable with the DC magnetic bias.File in questo prodotto:
