Abstract
PURPOSE: To increase the temperature performance of the oscillating frequency by using the piezoelectric substrate cut with a suitable angle for the crystal axis as the substrate of surface wave propagation.
CONSTITUTION: The oscillator 35 is constituted with the acoustic surface wave element 34 using the crystal plate 33 selecting the thicknesswise to the direction rotated from the Y axis by 38 degrees and providing the output electrodes 31 and 32. This oscillator 35 is connected to the amplifier 36, phase shifter 37 and amplifier 38 for the output of the element 34, and the output is positive-fedback to the input of the element 34. By using the crystal plate of 38 degree cut, at the center temperature in the usable temperature range, for example, around 25 degree C, the tilt of the temperature characteristics can be zeroed. That is, to the inclination of the characteristics in change of the frequency around 25°C is made equal to that of the surface wave propagation delay time characteristics around 25°C and the piezoelectric plate with the crystal axis for the purpose can improve the frequency versus temperature characteristics.
