  • Protective circuit for the input-side protection of an electronic device operating in the maximum frequency range
    Patent number: 8625247
    Abstract: The invention relates to a protective circuit (10) for the input-side protection of an electronic device (30) operating in the maximum frequency range from high-power interfering impulses in the working frequency range of the device (30), said protective circuit (10) between an input (11) and an output (18) comprising a first limiting circuit (12) having at least one gas discharge tube (GDT1, GDT2) for limiting high interference powers and a second limiting circuit (14, 16) disposed behind the first limiting circuit (12), said second limiting circuit having semi-conductor components (D1, . . . , D4) for limiting smaller interference powers. Protection from particularly high interference powers is achieved in that the first limiting circuit (12) comprises two gas discharge tubes (GDT1, GDT2) connected in parallel and preferably identical.
