Abstract 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 manufaetured by using this program, and good results are obtained.
