Wide band printed circuit board through connector
A through connector device is disclosed. The device may include a coaxial cable receiver portion defined by one or more surfaces, the coaxial cable receiver portion configured to couple to a center conductor portion of a coaxial cable, the center conductor portion of the coaxial cable protruding above a dielectric material of the coaxial cable. The device may include a beam lead positioned adjacent to the coaxial cable receiver portion. The device may include a planar transmission line contact pad configured to make electrical contact with a planar transmission line of a printed circuit board. The device may include a step configured to electrically and mechanically couple the beam lead to the planar transmission line contact pad, the step configured to create a gap between a bottom surface of the beam lead and a top surface of an outer conductor portion of the coaxial cable.
