The textbook was prepared at the Department of Electronics of the Faculty of Physics of Voronezh State University . The manual is devoted to the study of the parameters and characteristics of electromagnetic compatibility (EMC) of radio receiving devices of the microwave range . The determining value for the EMS of the radio receiver are the indicators of noise immunity of low-noise radio frequency amplifiers (MSW), the study of which is given increased attention. The concept of physical mechanisms of influence of intense interference on reception of radio signal is given. A system of parameters and characteristics of the EMS of the radio receiver and the MSE describing this effect is introduced. The issues of automation of measurement of parameters and characteristics of EMS. are considered The basic principles of constructing the theory of EMS MSHU of various types are discussed. Recommended for students of the 5th year of D/o and undergraduates studying in the specialty "Radiophysics and Electronics" and studying the discipline "Electromagnetic compatibility of radio electronic means". The manual will also be useful in studying the course "Physical Electronics" (3rd course d/o) in terms of deepening the ideas about nonlinear multi-signal modes of electronic microwave devices
