THREE-TURN SQUARE WAVE MICROSTRIP DELAY LINE PROTECTING 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, and the signal conductors are located symmetrically to it on the other side of the dielectric substrate, while the end of the second line conductor is connected in series with the beginning of the first conductor of the second delay line, identical to the first delay line. In this case, the end of the second conductor of the second line is connected in series with the beginning of the first conductor of the third delay line, identical to the first and second delay lines.

EFFECT: increased attenuation of the USP due to its decomposition into a sequence of twenty-seven pulses of smaller amplitude.
