Protection against ultrashort pulses based on a turn of meander microstrip line

Decomposition of an ultrashort pulse into a sequence of pulses with lower amplitudes in the turn of a meander delay line has been experimentally proved to be an effective method of protection against ultrashort pulses for electronic equipment. It has been shown that a signal at the output of a line can be minimized by means of equalization of amplitudes of the first three pulses. It has been achieved due to optimization of couplings between half turns of a line. The obtained attenuation of a pulse with duration of 40 ps (at half of the maximum signal level) is 6.3 times.
