The book discusses the properties of the structures of radio equipment elements, as well as the dependence of the parameters of the structure on its geometry and the properties of materials, analyzes the instability of parameters, as a result of external influences, and the spread of parameters, as a result of the instability of the technological process. Based on the consideration of the above issues, the limits and methods for managing design parameters are determined, the knowledge of which is a prerequisite for the design of radio equipment elements...
