ABSTRACT:
Fast-response electronic surge arrestors for protecting electrical equipment from the damaging effects of large amplitude, fast rise-time voltage transients. An electronic surge arrestor in accordance with the invention includes first and second transient suppression circuits arranged in parallel and coupled between a flat elongated microwave strip transmission line conductor and ground potential for dissipating transients of first and second polarities appearing on the conductor. Each of the first and second transient suppression circuits includes a fast-response Zener diode and a switching diode arranged in a serial, oppositely-poled fashion and having biased junctions for dissipating transients of the first and second polarity, respectively, while minimizing dissipation of signals in the UHF band which may be received or generated by the electrical equipment and also appear on the microwave strip conductor.
