The paper considers protection of radio electronic equipment against conductive excitation of an ultra-short pulse (USP) by using a serial connection of two modal filters (MF) of the same length, which have a passive conductor in the cutout of the reference plane. The amplitude at the output was reduced by 12.5 times in relation to the half of the e.m.f. with 50 Ω resistors at the ends of the passive conductors. The influence of boundary conditions at the ends of the passive conductors of two MFs was considered. For OC-SC, OC-SC the amplitude reduction by 70 times was achieved.
