DEVICE FOR MEASURING COMPLEX TRANSMISSION AND REFLECTION COEFFICIENTS OF MICROWAVE QUADRIPOLES WITH FREQUENCY CONVERSION Russian patent published in 2023 - IPC G01R27/28 

FIELD: radio measuring equipment.

SUBSTANCE: invention is used to measure the complex transmission and reflection coefficients of microwave devices with frequency conversion. The technical result is measuring the modulus and phase in the intermediate frequency range and increasing the accuracy of measurements of the parameters of complex transmission coefficients. The result is achieved by the fact that a device is proposed for measuring the complex transmission and reflection coefficients of microwave quadripoles with frequency conversion, containing a parameter meter for microwave quadripoles and a two-channel superheterodyne receiver, which differs from the prototype in that an external output connector of the microwave test signal generator, frequency stabilization unit, microwave signal divider, switch, second phase detector, first and second control units, second and third intermediate frequency generator, second signal ratio meter are additionally introduced.

EFFECT: measuring the modulus and phase in the intermediate frequency range and increasing the accuracy of measurements of the parameters of complex transmission coefficients.
