Abstract
A magnetostatic wave (MSW) signal-to-noise (S/N) enhancer includes a divider for dividing an input signal into a first and a second path signals, first and second microwave-MSW transducers for transducing the first and second path signals into the first and second path transduced signals, and a combiner for combining the first and second path transduced signals in opposite phase to each other. The first path signal contains a desired signal which is higher than a first saturation level and a noise component which is lower than the first path threshold power level. The first microwave-MSW transducer outputs the noise in linear operation and the desired signal in saturation operation. All the component signals of the second path signal including noise are lower than the second path threshold power level and are output in a linear operation by the second microwave-MSW transducer.
