<p>A resonator or resonator filter (134) has an output transducer (140) of typical design and conductance response and an input transducer (138) whose conductance response can be adjusted to offset adverse conductance response of the output transducer to provide an unique improved overall conductance response of the resonator or resonator filter, by forming the input transducer with one adjacent pair of electrodes (48,50) located substantially centrally and having a spacing forming a cavity (150) with a width of (N)λ/2 where N is an integer. </p> |
