Abstract :
A frequency tunable magnetostatic wave (MSW) straight edge resonator (SER) made by a yttrium iron garnet (YIG) film has been used as a selective frequency component in a resonating filter. MSW CPW (coplanar waveguide) transducers on silicon wafers and S-parameters have been measured at different DC magnetic bias fields, with a frequency tunability between 7.5 GHz and 11 GHz ca. An improvement of the performances for the SERs excited by CPW 50 Ω, transducers has been demonstrated.
