INTERFERENCE-RESISTANT TRANSMISSION SYSTEM WITH DIGITAL SELECTION UNIT AND AUTOMATIC MATCHING DEVICE ON DISCRETE ELEMENTS Russian patent published in 2021 - IPC H03H7/40 H04B1/02 

FIELD: radio communication technology.

SUBSTANCE: invention relates to radio communication technology and can be used in radio stations of the short-wave (SW) range, as well as in radio stations of other ranges, operating in conditions of concentrated interference. The technical result consists in increasing the noise immunity of the transmission system to interference induced into the antenna from the signals of powerful radio transmitting devices. An interference-free transmission system with a digital selection unit and an automatic matching device on discrete elements contains a high frequency generator (HFG), a bidirectional coupler, a matching circuit and an antenna, as well as a tuning unit, while the HFG contains a sinusoidal signal generator (SSG), a power amplifier and a switch, while additionally introduced a digital selection unit, made with the possibility of separating the useful signal and suppressing other spectral components while maintaining the phase relationships of the useful signal from both outputs of the bidirectional coupler, and a microprocessor device.

EFFECT: noise immunity increased.
