SC-Cut quartz resonators with suppressed b-mode |
摘要 |
Disc shaped quartz crystal resonators of plano-convex, plano-plano, and biconvex configurations have the b-mode resistance raised relative to the c-mode resistance by the proper choice of mounting geometry, thus suppressing the undesired b-mode in precision oscillator circuits without the use of added circuitry.
