ABSTRACT:
A surface-acoustic-wave parametric device includes in that a plurality of pumping electrodes arranged along a propagation path of surface acoustic wave. Values of DC bias voltages to be applied to the respective pumping electrodes for forming parametric interaction regions, or values of pumping voltages to be applied to the pumping electrodes, are differentiated so as to correspond to a desired frequency characteristic.
