Abstract
A frequency tunable magnetostatic wave (MSW) straight edge resonator (SER) made by a YIG film has been used as a selective frequency component in a micromachined resonating filter. Sparameters have been measured at different DC magnetic bias fields, with a frequency tunability between 2 GHz and 6 GHz ca.. An improvement of the performances for the SERs excited by micromachined microstrip transducers has been clearly demonstrated. Moreover, the utilization of silicon membranes to support MSW-SERs offers important openings toward the integration of magnetostatic wave devices with micromachined structures.File in questo prodotto:
