Abstract
A broadband directional coupler and method of constructing same is disclosed. The coupler is formed from a first and second coaxial cable each of which has an inner conductor surrounded by an insulating material and an outer conductive shielding sleeve about the insulating material. An elongated opening is formed in the outer conductive shield sleeve axially along a predetermined length of the cable. The insulating material in the elongated openings is formed with mating surfaces extending substantially parallel to the inner conductor along a predetermined length. The first and second coaxial cables are connected together along a predetermined length of the mating surfaces with the surfaces in juxtaposed contact and the shielding sleeves of the first and second cables fused together about the elongated opening.
