Multi-pin coax connectors (MDCX) have low VSWR of 1.25:1 up to 10 GHz (max mated pair). Each spring loaded contact has a maximum diameter of 0.125" fitted into low profile metalized housing.

Spring loaded High Frequency Micro-D Coax Connectors (MDHC) offer low VSWR up to 40 GHz (typ). These connectors have a constant 50 ohm airline impedance interface and are 30% smaller than our SCX coaxial connectors. Each coax contact has a maximum overall diameter of Ø.133" fitted into a low-profile metalized or plastic housing. MDHC coaxial contacts are a drop in alternative to Smiths Connectors MDCX RF contacts with increased frequency range from 10 GHz to 40 GHz.
