本专利的目的是提供一种结构简单性能良好的新型陶瓷滤波器,其特点是,在园柱形压电陶瓷中心埋入一根铂丝那样的高熔点导线,然后烧成,在园柱形压电陶瓷外边形成银电极再进行极化处理。就以下图所示的实际例子进行说明。图1和图2是二端滤波器,在钛酸钡、 The purpose of this patent is to provide a new type of ceramic filter with good structural simplicity which is characterized by embedding a high-melting-point wire such as a platinum wire in the center of the cylindrical piezoelectric ceramic and then firing the same in a cylindrical shape A silver electrode is formed on the outside of the piezoelectric ceramic for further polarization treatment. Explain the actual examples shown below. Figure 1 and Figure 2 are two-terminal filter, barium titanate,
