Frequency-Temperature Coefficients of Mass-Loaded Plate Vibrators.

摘要

The report considers a single thickness mode of a piezoelectric crystal plate,and relates both the characteristic frequencies and their temperature coefficients to the phenomenological material properties of the crystal and the electrode mass-loading. It is shown how mass-loading affects the frequency-temperature characteristics of the plate vibrator. Experimental results prove the existence of another factor,that depends on the electrode material,which contributes significantly to the temperature behavior.
