  • suitable measures are taken in the connector to counter-compensate for the mismatch. In both cases, reflections of the radio frequency signal along the signal transmission path are minimized.
  • the geometric dimensions of the individual components of the plug connection - i.e. H. the outer conductor shield, the optional support sleeve, the insulation element, the inner conductor contact element and the outer conductor contact element - must be coordinated with one another in the best possible way with the lowest possible manufacturing tolerance.

  • the individual components of an electrical cable - ie the inner conductor, the insulation element, the outer conductor shield and the cable jacket - are made from a specific material and have a specific geometric dimension.
  • the outer diameter of the insulation element is particularly important for the assembly process, since it should correspond to the inner diameter of the outer conductor contact element for impedance matching.
  • an associated outer conductor contact element with a suitable inner diameter must be produced. This requires a variety of designs, tools, manufacturing plans and machine programs.
