Two SAW stabilized oscillators with FM and PAM capability have recently been designed and breadboarded to provide 300 ppm frequency stability over a -70/spl deg/ C to +70/spl deg/C environment. The circuits are being developed for use in low cost, ex

It is known that the propagation characteristics of elastic waves are influenced by the nature of biasing stress distributions in the propagating medium. A knowledge of the magnitude of such effects plays an important role in improving the performanc

The calculus of variations has been used to obtain solutions for the statics tress distributions in circular quartz resonator blanks caused by forces acting along the blank diameter. The resulting static stress distributionsh ave been used with nonli

Shallow bulk acoustic wave propagation in piezoelectric crystals is reviewed from the standpoint of work reported to date. It is compared to bulk and surface acoustic waves as to properties and device potential. Singly and doubly rotated cuts are con

The first-, second-, and third-order temperature coefficients of the elastic stiffnesses and compliances of alpha-quartz have been derived from thickness mode resonances of double-rotated quartz plates employing Christoffel's theory of wave propagati
