The mathematical model of a complex reflection coefficient meter for microwave devices is designed using the direct frequency conversion method. The model is represented by two independent equation systems, which are allow calculating a module and a phase of the complex reflection coefficient by two different ways using discrete analysis of an amplitude and phase field distribution in a transmission line. The model makes it possible to increase of measuring accuracy by an averaging procedure for obtained results.
