Abstract
Abstract An electronic connector for connecting a coaxial cable to a microstrip transmission line or to a coplanar transmission line. The connector has a transition length which is long enough to be treated as a transmission line rather than as a lumped element. In one embodiment, the transition is linear. In a optimal embodiment for minimal distortion, the transition follows a cosine shape.
