  • Cascade electromagnetic pulse protection circuit for high frequency application
    Patent number: 8605404
    Abstract: The present invention discloses a cascade EMP protection circuit, which comprises an LEMP protection circuit and a fast-response protection circuit, wherein a symmetric capacitive varactor element is cascaded to the path of signal transmission. Thereby, the present invention can protect electronic devices against LEMP or EMP released by an electronic weapon (NEMP, HEMP, or PEMP).
    Type: Grant
    Filed: June 8, 2011
    Date of Patent: December 10, 2013
    Assignee: Chang Gung University
    Inventors: Liann-Be Chang, Jiun Yuh Chen
