A subminiature coaxial connector including a matched impedance plug and jack for coupling printed circuit boards, RF modules, coaxial cables, and the like, and minimizing RF or microwave signal losses and/or degradations. The plug and jack each comprises a coaxial structure including an outer tubular conductor and a center contact held in place by a dielectric sleeve within the outer tubular conductor. The geometries of these elements are such that when the plug and jack are fully joined, the elements are coextensive and butt-mated, without steps, gaps, or other discontinuities. By combining structural functions into the electrical conductors, the present invention allows for fewer parts and shorter mating distances than is available in the prior art. Despite the small Size 20 connectors that are achievable with the present invention, low voltage standing wave ratios (VSWR's) can still be observed through 67 GHz, with theoretical cutoff frequencies in excess of 100 GHz.
