Overtone crystal
WebIf a crystal has a fundamental frequency of 10 MHz, it can also oscillate at 3, 5, 7, etc times the fundamental frequency. Therefore, the oscillator can oscillate at 30 MHz, 50 MHz, 70 MHz, etc. These are the frequency's overtones. Webwhere n is the overtone number and C is a constant that depends on the property of the crystal used. Equation 1, typically referred to as the Sauerbrey equation, constitutes the basic principle of QCM technology. 2 For a 5 MHz AT-cut quartz crystal at room temperature, C is approximately equal to 17.7 ng/ (cm 2 ·Hz).
