INTERFERENCE-PROOF TRANSMISSION SYSTEM WITH AUTOMATIC MATCHING DEVICE USING A WIDEBAND SIGNAL Russian patent published in 2022 - IPC H04B1/02 H03H7/40 

FIELD: radio communication engineering.

SUBSTANCE: invention relates to radio communication engineering and can be used in radio stations of the shortwave (SW) and ultrashortwave (USW) range, as well as in radio stations of other bands operating in conditions of concentrated interference. The interference-proof transmission system with an automatic matching device using a broadband signal additionally contains the first incident wave channel level analyzer (9), the second reflected wave channel level analyzer (14), the first (7) and second (8) delay blocks. The high-frequency signal generator (1) additionally contains a broadband signal generator (4) and a modulator (3). The incident wave level analyzer (9) and the reflected wave level analyzer (14) consist of a multiplier (10.1), (10.2) and a radio receiver (11.1), (11.2.) connected in series.

EFFECT: increasing the immunity of the transmission system to interference induced into the antenna from the signals of powerful radio transmitting devices, including for cases where the frequencies of the interfering signals are close to the tuning frequency or coincide with it.
