  • Isolated shield coaxial surge suppressor
    Patent number: 6975496
    Abstract: A surge protection device is disclosed that includes a conductor for receiving an rf signal and a dc current, a first shield having a lumen configured to accommodate at least a portion of the conductor, and a second shield having a lumen configured to accommodate the first shield so that a portion of the first shield is positioned within the lumen of the second shield. The surge protection device further includes a dc blocking device, coupled to the conductor, for attenuating the dc current, a device, coupled to the conductor, for diverting the dc current to the second shield, and a dielectric disposed between the first shield and the second shield for preventing the dc current from traveling from the second shield to the first shield.
    Type: Grant
    Filed: March 20, 2003
    Date of Patent: December 13, 2005
    Assignee: PolyPhaser Corporation

  • Surge suppressor device
    Patent number: 6236551
    Abstract: An apparatus and method for protecting hardware devices using a spiral inductor. The surge suppressor protects hardware devices from electric surges by isolating the radio frequency from an inner conductor. The surge suppressor includes a housing, an inner conductor, a surge blocking device, and a spiral inductor. The surge blocking device is inserted in series with the hardware devices for blocking the flow of electrical energy therethrough. The spiral inductor is coupled to the surge blocking device and is shunted to ground for discharging the electrical surge.
