Current inhibiting RF connector for coaxial/jumper cables
A connector for coupling a coaxial cable to an interface port comprising a capacitor segment configured to interpose a center conductor of a coaxial cable and an RF interface and an outer conductor segment extending over and electrically shielding the capacitor segment. The capacitor segment comprises an inner and outer pin having a dielectric insulator therebetween and is configured to electrically connect an inner conductor of the coaxial cable to the RF interface port. The capacitor segment facilitates the passage of RF energy from the inner conductor of the coaxial cable to the RF interface while inhibiting the passage of electric current through the capacitor segment to the RF interface.
