Abstract:

A coaxial transmission line structure having a center conductor section having an input contact and an output contact the output contact being larger than the input contact, the center conductor having a plurality of different geometrically shaped, electrically conductive layers having sizes progressively increasing from the input contact to the larger output contact to conductor transition from the input contact to the larger output contact, the electrically conductive layers being electrically interconnected by staggered microvias passing through dielectric layers to the center, and (B) an outer conductor section disposed about, coaxial with, and electrically isolated from, the center conductor by the dielectric layers.
