摘    要:介绍了低插损窄带型10.7 MHz压电陶瓷滤波器的一种设计制作方法。结合压电陶瓷能陷模理论,通过对滤波器分割电极设计和制造工艺控制技术的研究,强调了工艺控制的重要性。产品达到日本村田同类产品水平,对国产化窄带型10.7 MHz压电陶瓷滤波器的研发和生产具有十分重要的意义。认为选用高Qm值压电陶瓷材料、分割电极和耦合电容的设计、焊接和点蜡工艺的控制等是研制低插损窄带型10.7 MHz压电陶瓷滤波器的重点。

关 键 词:窄带滤波器  插入损耗  陶瓷材料  电极设计  工艺控制

Abstract:Presented is the design and manufacturing technology for the ceramic filter of low insertion loss and narrow bandwidth working at 10.7 MHz. The design of divided electrode and the manufacturing process-control were researched based on the theory of the piezo-ceramic energy trap mode. The performances of acquired filters are almost same as those of the Murata products of the same kind. High Qm PZT material, design of divided electrode and coupling capacitors, and process control of soldering and wax-application are the important factors for the filter.
Keywords:narrow band filter  insertion loss  ceramic material  electrode design  technology control
