摘要
本文校系统地导出宽带机械滤波器的设计公式和首次成功地采用方片厚度弯曲振动模式制成的低频宽带机械滤波器，其相对带宽达37％，超过了通常认为的机械滤波器最大相对带宽的范围。文末给出了设计实例。
In this paper, design formula of wide-band MF is given systematically, Low Frequency wideband MF made by mica thickness twisted vibration, mode is also given. Relative bandwidth is 37%, which is beyond maximum relative bandwidth in common knowledge. Finally, design example is given.
