谐波晶体
Since the 3rd overtone crystal resonator has high Q value, less absorb frequency and good drop characteristic, it is usually applied on some particular requirement circuit.
三次泛音49U/S石英谐振器因Q值高、频率牵引小、跌落性能好而被一些有特殊要求的电路所采用。
100.450 MHz 5th overtone temperature compensated crystal oscillator is developed. The oscillator is made up of 450 kHz ceramic oscillator, 100 MHz 5th overtone crystal oscillator, mixer and crystal filter.
应用新的温度补偿方法研制了100.450MHz五次泛音温度补偿晶体振荡器,该振荡器由450kHz陶瓷振荡器,100MHz五次泛音晶体振荡器,混频器,晶体滤波器组成。
