Abstract: A coaxial cable based electronic component or circuit is described. The circuit comprises one or more coaxial cables, each having an inner conductor which is surrounded by an insulating material and an outer conductive shielding sleeve is disposed about the insulating material. A window of predetermined size is made in the outer conductive shielding sleeve for access to the inner conductor for incorporating same as an integral part of an electronic component or circuit. The insulating material forms at least part of an electrically insulating support and electrical shield for the electronic circuit. The conductor has opposed terminal ends for connection thereto.

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.
