The article considers a simulator/analyzer that provides simulation modeling of microwave ampli-fiers and oscillators in accordance with their technical specifications, followed by the measurement of complex load reflection coefficients of the active component of these devices for their design. It also considers a method of measurement of these parameters and a method of calibration of the simula-tor/analyzer providing transfer of measurement results from the coaxial measuring line of the simula-tor-analyzer to the microstrip line. In addition, the article considers a method for analyzing the stability of the active component in the space of complex reflection coefficients of its loads, which facilitates their selection in the simulation of amplifiers and oscillators.

The paper considers mathematical models of an amplifier, an unstabilized generator, and an autogenerator which take into account the stability parameters of the active component. The developed library of mathematical models provides automation of simulation modeling of amplifiers and autogenerators by means of a simulator-analyzer in the CAD system.
