FOUR-TURN FACE-COUPLED SQUARE WAVE DELAY LINE THAT PROTECTS AGAINST ULTRA-SHORT PULSES Russian patent published in 2023 - IPC H03H7/30 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering. The effect is achieved by the proposed delay line consisting of one reference conductor, two signal conductors parallel to it and to each other, connected to each other at one end, and a dielectric medium consisting of a dielectric substrate and ambient air, the reference conductor of which is located on one side. dielectric substrate with one of the signal conductors, and the second signal conductor is located symmetrically to the first relative to the dielectric substrate, while the end of the second signal conductor of the line is connected in series with the beginning of the first signal conductor of the second delay line, consisting of identical elements, while the end of the second signal conductor of the second line delay is connected to the beginning of the first signal conductor of the third delay line, consisting of identical elements, and the fourth delay line, the corresponding parameters are selected for each line.

EFFECT: increased attenuation of the USP due to its decomposition into a sequence of two hundred and fifty six pulses of smaller amplitude.
