摘要
仅用一种压电陶瓷材料,通过压缩和展宽压电陶瓷谐振器的谐振频率间隔,采用多种电路结构,压电陶瓷滤波器3dB相对带宽已达到0.8—33.6%的范围.
Through compacting and expanding the intervals of piezoelectric ceramic resonators, but using only one type of ceramic material and many kinds of circuits, the relative bandwidth (at 3dB) of the ceramic filters has atlained to 0.8-33.6%.
