Abstract
Abstract A DIN press-fit coaxial connector having a press-fit center pin and a modified BNC coaxial connector having a hollow center pin are mounted back-to-back on opposite sides of a backplane with the respective center pins of the two coaxial connectors aligned along the same linear axis and in conductive press-fit engagement with each other within a waveguide defined by a conductive-material-coated center hole in the backplane. The diameter of the center hole is dimensioned in relation to the outside diameter of a cylindrical hollow portion of the center pin of the modified BNC coaxial connector to impedance match the connection between the modified BNC coaxial connector and the DIN press-fit coaxial connector. The center hole in the backplane is empty and thereby has the dielectric constant of air, which enables the diameter of the center hole to be small enough that first and second sets of apertures can be disposed in the backplane outside the boundary of the center hole for receiving the respective sets of mounting pins of the DIN press-fit coaxial connector and the modified BNC coaxial connector.
