METHOD FOR MEASURING THE FREQUENCY OF A GENERATOR SIGNAL AND A DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2022 - IPC G01R23/14 G01N22/00 H01P1/08 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and can be used to measure the physical parameters of gases by radio wave methods in a wide range of pressures. The device for measuring the frequency of the generator contains a housing filled with high-pressure gas, a generator installed in it, a first hermetic dielectric window, a first power divider, a frequency multiplier, a first bandpass filter, a local oscillator, a second power divider, a first mixer, a second bandpass filter connected in series, a transmission filter, the first transmitting horn antenna, the first receiving horn antenna installed in the first hermetic dielectric window. The housing also has a second sealed dielectric window with a second transmitting horn antenna and a second receiving horn antenna installed in it. The device also contains a second mixer and a third band pass filter connected in series, the output of which is connected to a frequency meter. The second output of the first power divider is connected to the second input of the first mixer. The second output of the second power divider is connected to the second transmitting horn antenna. The second receiving horn antenna is connected to the second input of the second mixer, and the first receiving horn antenna is connected to the first input of the second mixer.

EFFECT: implementation of the function.
