The algorithm for determination of module and argument of complex reflection coefficient (CRC) of microwave circuits, which is based on digital processing of the measurement signal in the spectral domain, is proposed.
The homodyne detection of useful signal at equipment design, is proposed. The possibility of discrete phase change for frequency shift of test-signal is suggested. The equipment design for amplitude and phase progression is described. The results of experimental investigations are presented.
Full calibration algorithm based on mathematical model of switching transducer is developed. The system of calibration equations is solved in two ways. The second way offers advantage to make calibration procedure with a set of short circuits
