DEVICE FOR MEASURING COMPLEX TRANSMISSION AND REFLECTION COEFFICIENTS OF MICROWAVE DEVICES WITH FREQUENCY CONVERSION Russian patent published in 2018 - IPC G01R27/28 

FIELD: measuring equipment.

SUBSTANCE: invention relates to a radio measuring technique and can be used to measure the complex transmission and reflection coefficients of microwave devices with frequency conversion. Device for measuring the complex coefficients of transmission and reflection of microwave devices with frequency conversion consists of a measuring device for the four- and a two-channel superheterodyne receiver, an intermediate frequency amplifier, an adjustable attenuator, a signal ratio meter, two directional couplers and two switches are additionally introduced. Connections of newly entered and common elements with the prototype form a device that allows to exclude the amplitude-phase error and thereby increase the accuracy of measurements.

EFFECT: technical result is improvement of accuracy of measurements.
