ABSTRACT:
A compact, low-cost magnetostatic wave device which can serve as an S/N enhancer or a filter. The magnetostatic wave device includes a ferromagnetic base; at least one transducer having a portion arranged adjacent to one surface of the ferromagnetic base and another. portion arranged adjacent to the other surface of the ferromagnetic base; an input terminal with one side connected to one end of the transducer and the other side grounded; and an output terminal with one side connected to the other end of the transducer and the other side grounded. The ferromagnetic base is preferably disk-shaped.
