FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering and can be used to protect electrical circuits from ultrashort pulses. Disclosed is a microstrip line consisting of a reference conductor in the form of a conducting layer, a dielectric substrate on the reference conductor, a signal conductor in the form of a strip on the substrate and a grounded conductor from above, connected at the ends to the reference conductor, with line parameters providing decomposition of the USP acting between the signal and reference conductors into pulses of equal amplitude. Upper earthed conductor is connected to the reference conductor at points dividing the line into three sections so that the second section is twice as long as the first one, and the third section is four times longer than the first one.
EFFECT: increased attenuation of USP.
