摘要
本文是在深入研究单片晶体滤波器理论和等效电路的基础上,首次利用单片晶体滤波器的综合设计与网络分析相结合的方法将过去人工设计和反复试验的过程全部在计算机中实现。在设计程序中,为了避免解超越方程给出了半经验公式,并对一些系数进行了修正。在分析程序中,采用了模块技术和级联矩阵方法。本程序是在PC机汉字操作系统下用BASICA编写的。最后给出了用本程序设计制作的几种单片晶体滤波器。
Based on studying deeply the Monolithic Crystal Filter (MCF) theory and itsequivalent circuit, the design and analysis of MCF by computer is described. In the design program, the quasi-empirical equation is given and some coefficients are modified for avoiding to compute transcendental equation. The building block technology and step connecting matrix method are used in analyzing program, so the program procedure becomes more simple and the computation speed is increased. Finally some kinds of monolithic crystal filters are designed and manufactured by using this program, and good results are obtained.
