Nonlinear frequency-selective device on magnetostatic waves

Experimental investigation results of the suppression of various power level signals passing through a "microstrip resonator-ferromagnetic film" system in the case of magnetostatic backward volume wave excitation are demonstrated. A model is presented describing the nonlinear characteristics of such a device in the form of two coupled oscillatory circuits whose parameters depend on the input signal power levels. The nonlinear characteristics of the investigated device were obtained by simulation and are compared with experimental values.
