FIELD: electrical engineering.
SUBSTANCE: four terminal network is made as a complex of reactive and resistance elements, then a double-pole non-linear element is introduced and connected into transversal circuit between the source of high-frequency signal and input of four terminal network; load is connected to output of four terminal network, non-linear element is connected to the source of low-frequency control signal; conditions for provision of minimum reflected signal are met in sequence at preset number of frequencies at simultaneous amplitude variation of control signal.
EFFECT: expansion of areas for physical realisability as areas for variation of actual and idle components of resistance of signal source and load and within their limits full matching of resistance for signal source and complex load resistance is ensured in sequence at preset number of frequencies.
