Abstract

A possibility of improving protective characteristics of transmission lines by cascading of multiconductor modal filters (MFs) with different geometric configurations is studied. Three-conductor MFs based on an asymmetric coaxial structure and a microstrip line and four variants of cascade structures consisting of two and three sections of such MFs are considered. Simulation of the time response to an ultrashort pulse (USP) and parametric optimization are performed. Attenuation of USP by a factor of 27.4 is achieved.

Keywords

transmission line, multiconductor modal filter, ultrashort pulse
