The book deals with the design and quality control of microwave devices using simulation and measurement methods. It describes principles for designing simulators of microwave amplifiers and oscillators that provide simulation modeling of these devices in accordance with the technical specifications for their design. In addition, it shows how simulators can be used for accurate and adequate measurements of the parameters of the simulated devices required for their subsequent design. The book also addresses the development of effective methods for controlling the quality of complex technical products (including microwave amplifiers and oscillators). The simulation method and control modeling algorithms proposed here can be used to analyze existing and plan new effective methods of measuring control that minimize the costs associated with control.The text will be useful for developers of measuring systems and methods, as well as quality experts involved in the design and manufacture of technical products. In addition, it will appeal to researchers, teachers, and both undergraduate and graduate students.
