DEVICE FOR SUPPLYING NOISE GENERATOR SIGNAL TO COAXIAL-WAVEGUIDE CHANNEL OF RADAR STATION Russian patent published in 2020 - IPC H03B29/00 

FIELD: physics.

SUBSTANCE: invention can be used for use in microwave devices of radar stations (RS) as a noise generator (NG) communication device with a coaxial-waveguide channel. Essence of the invention consists in the fact that the device for feeding the NG signal into the coaxial-waveguide channel of the radar station comprises a NG, an external conductor and a central conductor of the coaxial-waveguide channel, communication element made in the form of a tuning probe (pin) installed in the hole of the external conductor, equipped with a metal disc with an insulator on the end and a matching resistor connected by one terminal to the tuning probe (pin), and by another terminal - with core with thread having electric contact with external conductor of coaxial-waveguide channel due to that tuning probe (pin) is rigidly installed through dielectric in core with thread, interacting with internal thread of bushing, which, in its turn, is rigidly installed on external conductor of coaxial-waveguide channel. At the same time tuning probe (pin), moving through hole in external conductor, changes connection of NG with central conductor of coaxial-waveguide channel.

EFFECT: technical result is increase in dynamic range of adjustment, providing constant coefficient of standing wave voltage (CSWV) ratio in NG signal feed circuit, reducing device units.
