Rectangular thickness shear quartz crystal oscillator

Rectangular thickness shear quartz crystal oscillator

A thickness shear quartz crystal oscillator has two major surfaces which extend in the direction the of X axis of the crystal and which are 5mm to 10mm long. X-Z plane defined by the X axis and Z axis of the crystal is rotated about the X axis by 35 DEG 08' to 35 DEG 16' so that the major...

Zusammenfassung:A thickness shear quartz crystal oscillator has two major surfaces which extend in the direction the of X axis of the crystal and which are 5mm to 10mm long. X-Z plane defined by the X axis and Z axis of the crystal is rotated about the X axis by 35 DEG 08' to 35 DEG 16' so that the major surfaces are parallel to an X-Z' plane defined by the X axis and an imaginary Z' axis inclined to the Z axis at 35 DEG 08' to 35 DEG 16'. One of the major surfaces is displaced in the direction of the Z' axis to thereby cause the side faces of the oscillator to incline at an angle of 4 DEG to 6 DEG .
