CA 2391789
A S/N enhancer using the magnetostatic wave signal is disclosed. The S/N enhancer comprises a balun coupler for dividing an input signal into a first and second signals having the same power, the second signal having the phase difference of 180 degree with respect to the first signal; a saturation magnetostatic wave filter for receiving the first signal output from the balun coupler, converting that into a magnetostatic wave signal, and converting the magnetostatic wave signal into a signal having a shape of the first signal, wherein a power of the magnetostatic wave signal is saturated if the first signal has a power of equal to or more than that of a noise signal; a linear magnetostatic wave filter for receiving the second signal from the balun coupler, converting that into a magnetostatic wave signal, and converting the magnetostatic wave signal into a signal having a shape of the second signal, wherein the received second signal is converted into the magnetostatic wave signal having an energy linear to a power of the input signal; and a power synthesizer for synthesizing respective signals output from the saturation magnetostatic wave filter and the linear magnetostatic wave filter.
