Abstract

PURPOSE:To make an AT cut quartz oscillator small-sized, and also improve both the frequency temperature characteristics and the spurious characteristics, by setting the ratio of length, width and thickness of said resonator within the prescribed range. CONSTITUTION:The AT cut quartz oscillator is made in the form of simple rectangle, bi-bevel, plano-bevel, bi-convex, plano-convex rectangle, etc., and the ratio to its length (l), width W and thickness (t) in dimensions is made 6.0<=l/t<=14.5, 3.1<= W/t<=3.5, respectively. According to said range, it is possible to obtain the intrinsic frequency temperature characteristics of the AT cut quartz oscillator without being influenced by spuriousness, by which the frequency is decided by width in dimensions.
