本文针对陶瓷滤波器生产和使用中的重大课题阻抗一致性问题,着重从理论上进行了分析,找出了陶瓷振子参数的分散性和各基本节之间阻抗的不一致性对陶瓷滤波器性能的影响,特别是对阻抗一致性的影响,导出了计算公式,并在此基础上提出了控制陶瓷滤波器阻抗一致性的方法.从而进一步完善了现有的关于陶瓷滤波器的设计理论.最后进行了初步的实验工作. In this paper, aiming at the issue of the consistency of the major issues in the production and use of ceramic filters, this paper mainly analyzes the theory and finds out the dispersion of the ceramic oscillator parameters and the inconsistencies of impedances among the basic sections. Influence, especially on the impedance consistency, the calculation formula is derived, and on the basis of this, a method of controlling the impedance consistency of the ceramic filter is proposed, so as to further improve the existing design theory of the ceramic filter. The preliminary experimental work.
