晶体滤波器是一种性能良好的选频器件,当其应用于各种通讯及测试设备时,对于提高设备的抗干扰能力及测量精度均有独特的效果。在设计晶体滤波器时,除了要合理的选择一些特征频率及晶体的基本参数外,很重要的还在于对其衰减特性的设计、晶体滤波器典型的衰减性曲线如图1所示。
Crystal filter is a good performance of frequency selective devices, when used in a variety of communications and test equipment, to improve the anti-interference ability of equipment and measurement accuracy has a unique effect. In the design of crystal filters, in addition to a reasonable choice of some of the basic characteristics of the frequency and crystal parameters, it is also important to its attenuation characteristics of the design, the crystal filter typical decay curve shown in Figure 1.
