Abstract
A transition circuit includes a conductive pin; a first dielectric member disposed about a first portion of the conductive pin; and a second dielectric member disposed about a second, different portion of the conductive pin and having a first surface disposed adjacent to a first surface of the first dielectric member. A conductive wall is disposed about and contiguous to a second surface of the first dielectric member and a second surface of the second dielectric member. A strip conductor is disposed on a third surface of said second dielectric member and coupled between said conductive pin and said conductive wall.
