Abstract

A circulator preferably fabricated using thin film techniques. Broad-band isolation and insertion loss characteristics are obtained in the gigahertz frequency range by replacing the conventional series resonant circuit typically employed in circulation, with three symmetrically arranged lumped parameter LC circuits fabricated by thin-film techniques and having the junctions of the LC elements interconnected through conductive paths, such as inductors, for example.
