FIELD: physics.
SUBSTANCE: use: to reduce phase noise of microwave source. Essence of the invention lies in the fact that the device for reducing phase noise of the microwave signal includes an analogue microwave phase shifter, resonators and an amplifier, the output of the phase changer is connected to a divider, one output of which is output of device, and to second output is connected input of 3-decibel divider with two outputs, near outputs of which resonators are arranged, and to output of each resonator is connected detector input, outputs of detectors are connected to inputs of differential amplifier, output of amplifier is connected to input of low-pass filter, and output of filter is connected to control input of analog microwave phase shifter, at that resonant frequencies of resonators are upset at equal values of frequency from frequency of input signal in different directions.
EFFECT: enabling suppression of phase noise in a microwave source.
