摘要： The present invention provides a thin film device in which parasitic capacitance can be reduced as much as possible. In the case where a coil is provided so as to be insulated between an upper magnetic film and a lower magnetic film, the coil is constructed so that the cross section of the coil has the minimum width at its edges closest to the upper and lower magnetic films. Parasitic capacitance generated between the coil and the lower magnetic film and parasitic capacitance generated between the coil and the upper magnetic film are reduced and, in addition, parasitic capacitance generated between turns of the coil is also reduced.

摘要： A surface acoustic wave (SAW) device includes a plurality of SAW filters connected in cascade. An impedance matching element in the form of a SAW resonator is interposed between two adjoining SAW filters. Each filter includes a first piezoelectric substrate having a first electromechanical coupling factor and the resonator includes a second piezoelectric substrate having a second electromechanical coupling factor. The second electromechanical coupling factor is greater than the first factor so that the inductive band of the SAW resonator is wider than the pass band of the SAW filter. The device affords improved filter properties including an increased fractional bandwidth and an increased out-of-band attenuation.
