Claim:
1. A non-magnetic material frequency selective limiter circuit, comprising: an input configured to receive an input signal; an output configured to output an output signal; a first resonator oscillating at a fundamental frequency to pass a signal having a frequency ω for an input signal having the frequency ω; a second resonator oscillating at one half of the fundamental frequency to pass a signal having a frequency ω/2 for an input signal having the frequency ω; a non-linear coupling component non-linearly and parametrically coupling the first resonator and the second resonator, wherein the first resonator, second resonator and the non-linear coupling component are arranged so as to reduce the amplitude of an output signal for an input signal of frequency ω when an input signal amplitude is above a voltage threshold value, by converting part of the input signal to a signal at the frequency ω/2, wherein the first resonator, second resonator and the non-linear coupling component are formed of non-magnetic materials, wherein the first and second resonators are arranged to cross each other.
