摘要
采用一种新的设计方法来研制一种小体积的窄带陶瓷滤波器。此种方法仅采用一种标准的压电振子 ,并与一定的电容网络相结合 ,就可实现通常由串、并联两种振子构成的滤波特性。本文探讨了这种压电振子的特性以及电容网络的选择与近似计算方法。
The newly developed small filter is comprised of some standard piezoelectric ceramic resonators and a special capacitor network while the conventional filters consist of resonators connected in serial or parallel. The features, choice of capacitor network and approximative calculation are discussed.(2 refs.)
