Methodical instructions for the implementation of the laboratory workshop "Measurements on microwave" (specialty 013800, radiophysics and electronics) . Description of laboratory work "Transformer of complete resistances" and methodological instructions for its implementation. The work introduces students to the physical processes that occur in the coordination of elements of the microwave path, having different wave resistances, using a transformer of complete resistances. On the basis of the acquired knowledge, students can successfully study radio equipment, solve issues of coordination in the development of microwave devices and devices. The presented material corresponds to modern programs in radio-physical specialty and facilitates independent work of students.
