Abstract
A limiting filter has nonlinear signal limiting devices integrally connected to the filter structure so that as the power level of input signals increase the nonlinear signal limiting devices decrease their impedance in response thereto, detuning the filter. Filter isolation thus becomes a function of both frequency and input power.
