  • Apparatus and method for a conductive elastomer on a coaxial cable or a microcable to improve signal integrity probing
    Publication number: 20130240247
    Abstract: A method and structure for improving signal integrity probing. A coaxial or a microcoaxial cable is threaded through an optional alignment substrate where the cable is used to support or align the cable or an array of cables. A conductive elastomer is placed on a cable or a microcoaxial cable to improve signal integrity probing.

  • Embedded isolation filter
    Publication number: 20120081867
    Abstract: The present disclosure relates to reducing unwanted RF noise in a printed circuit board (PCB) containing an RF device. An isolation filter is embedded in a PCB containing an RDF device. By placing the isolation filter as close as possible to the RF device in order to dramatically reduce unwanted RF noise due to unavoidable coupling between Vias and planes in the PCB structure.

  • Reduced contact resistance on a SLIC
    Patent number: 5148475
    Abstract: A SLIC includes in separate and distinct contacts for the output of a tip and ring line driver and their feedback resistors to the balancing resistor of the appropriate tip and ring line. Thus, a Kelvin contact arrangement is produced providing a compensation for the contact resistance of a single connection.
