Abstract

The nonlinear characteristics of SAW resonators have been of great interest recently. We present a new nonlinear solution algorithm for the f-2f nonlinear coupling phenomenon in SAW IDT resonators. Specifically we have applied our algorithm to obtain the f-2f frequency response of the lithium niobate YX-127o SAW IDT resonators. Lithium niobate was chosen because a complete set of its nonlinear material constants was known and published in the literature. The algorithm consisted of solving the nonlinear finite amplitude model in the time domain to obtain the time dependent response, and then performing a fast Fourier transform of the time dependent response. In order to minimize the transient response, the initial conditions for the time domain solution were obtained from the frequency response of the linear model. Results were presented for a one-electrode IDT SAW resonator at increasing drive voltages. The charge on the electrode IDT for the nonlinearly generated 2f mode increased with the square of the magnitude of f mode drive level voltage.
