摘　　要：介绍了6.5 MH z压电陶瓷滤波器的设计原理和制备工艺。通过对锆钛酸铅(PZT)压电陶瓷材料的改性,确定了滤波器陶瓷材料的配方,通过对分割电极的设计,实现了二重模滤波器的电容耦合;经过不断的试验和工艺改进,使产品性能达到了预期的目标。The design principle and manufacturing technology of the 6.5 MHz piezoelectric ceramic filter are introduced. The formula of the filter＇s ceramic material is determined through modifying Pb（Zr,Ti）O3（PZT） piezoelectric ceramic. The divided electrode is designed and the two-mode filters work well with capacity coupling. Satisfying performance parameters of the filter are achieved through many trials and technological improvement.
