1. A limiter for limiting a high frequency signal, comprising a plurality of transmission line sections connected in succession, each transmission line section comprising at least one series inductance coupling an input to an output of the transmission line section, and two oppositely-poled parallel-connected shunt diode arrays coupled at the output of the transmission line section to limit voltage of said signal at said output;

  • wherein the diode arrays comprise different numbers of diodes, connected in series, with the number of series diodes of the arrays decreasing progressively for the plurality of transmission line sections from an input of the limiter to an output of the limiter.
