The article presents the mathematical models of the basic stages of machining of coaxial ceramic resonators and construction of ma-thematical model of coaxial ceramic resonators. These mathematical models allow sizing up electrodynamics parameters (Q-factor, impedance, a resonant frequency) of coaxial ceramic resonators. The account of constructive-technological and electrophysical para-meters of coaxial ceramic resonators when designing band-pass microwave filters based on them has been considered. It has been shown, that the technique of taking into account of spreads of constructive-technological and physical parameters in aggregate with modeling of elements and expected results of technological processes (roughness of internal and external surfaces of resonators) generally allows estimating possible values of key specifications of microwave filters.
