Description
Summary:A highly effective microwave convolver with extended frequency range is proposed and experimentally tested. This convolver uses nonlinear interaction of two dipolar spin wave (or backward volume magnetostatic wave) signals contrapropagating from the ends in a ferrite film placed inside an open dielectric resonator. The output signal, proportional to the convolution of the input signals, is received by the resonator, and is transmitted to a load through a regular waveguide. The proposed convolver does not have a strict upper limit for signal frequency, and at a signal frequency of 4.67 GHz has a record value of bilinearity coefficient of B=−11.7 dB W.
