ABSTRACT:
In the present invention magnetostatic wave (MSW) filters of the delay line and resonator type responsive to multimode MSW signals trap a desired MSW mode of the signal and attenuate untrapped modes of the signal in order to provide a higher order band rejection characteristic. In a preferred embodiment a low loss YIG film is disposed on a substrate. An apertured metallization layer on the YIG film defines a region of MSW propagation within the aperture and a metallization layer at the opposite side of the YIG film traps a selected MSW mode in said aperture. A region of high attenuation for MSW waves adjacent the desired propagation region absorbs untrapped MSW waves.
