Abstract:
1. A self-activating power limiter having an adjustable limiting threshold, the limiter including: (a) at least one switching element, each having a control input, a signal input, and an output; (b) each switching element having a first capacitive coupling element electrically connected from the signal input of such switching element to the control input of such switching element; (c) each switching element having a second capacitive coupling element electrically connected from the control input of such switching element to the output of such switching element; and (d) at least one control voltage source electrically coupled to the control input of the at least one switching element to adjustably control the limiting threshold of the limiter; wherein each switching element is in a non-conductive state while the signal input is below a selected level determined by the limiting threshold, and in a controlled variable impedance state while the signal input is above a selected level determined by the limiting threshold, the signal input being limited while the switching element is in the controlled variable impedance state.
