用一个反馈电路能使弹性表面波器件具有好的温度稳定性。反馈电路包括一个用于参考信号的相位比较器和一个沉积的薄膜加热器。在一个YZ铌酸锂试验延迟线中,当环境温度由25℃变到35℃时,相位变化所对应的最大温度变化为±0.017℃。
A feedback circuit allows SAW devices to have good temperature stability. The feedback circuit includes a phase comparator for the reference signal and a deposited film heater. In a YZ lithium niobate delay line, the maximum temperature change corresponding to the phase change is ± 0.017 ° C when the ambient temperature changes from 25 ° C to 35 ° C.
