Abstract

The synchronous two-port resonator can be used for the determination of SAW parameters, including velocity, electromechanical coupling coefficient, and reflection coefficient of one strip. These parameters can be determined from a comparison between the measured and calculated transfer functions of the resonator. Using this technique, the SAW free surface velocity of the 45 degrees XZ-cut of lithium tetraborate (Li(2)B(4)O(7)) crystal was found to be equal to 3436 m/s. The other measured parameters agree well with the values found in the literature.
