The propagadition of waves of finite amplitude in ultrasonic resonators with planar piezoelectric transdusers is researched. An analytical expression for amplitude-frequency characteristic of ultrasonic resonators is found on the basis of solution to the equation of nonlinear waves in dissipation medium and to the equations of piezoelectric effect. The achieve results will give a possibility to evaluate the influence of nonlinear effects on the accuracy of ultrasonic measurements in the 0.1 to 1 MHz range and can be used for calculation of nonlinear parameter of research medium.
