A nonlinear microwave signal processor based on the parametric interaction of a microwave dipolar spinwave pulse, propagating in an yttrium-iron garnet (YIG) film waveguide, with a non-stationary (pulsed) electromagneticpumping is proposed and practically realized. The proposed processor amplifies input pulsed microwave signals by up to30 dB, performs operations of phase conjugation, time profile inversion, and controlled time delay of up to 1 μs.
