Investigation of Resonanse Features of SAW Transducer
AbstractUsing equivalent circuits there was created SAW transducer mathematical model, that evaluates SAW propagation losses and second order effects. With the help of created mathematical model there was investigated what influence on transducer impedance parameters have second order effects and loss components. There was defined that piezoelectric material losses and air loading losses have insignificant influence on transducer impedance, thus when in is necessary to decrease calculation volume, they mey not to be taken into account. Input impedance of SAW transducer is investigated.
