Abstract:
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.

A S/N enhancer using the magnetostatic wave signal is disclosed. The S/N enhancer comprises a balun coupler for receiving an first signal an d dividing two second signals having the same power and the phase difference of 180 degree; a saturation magnetostatic wave filter for receiving one of t he two second signals output from he balun coupler, converting that into a magnetostatic wave signal, and oppositely converting the magnetostatic wave signal, wherein the power of the magnetostatic wave signal is saturated if t he received second signal has the power of equal to and more than that of a noi se signal; a linear magnetostatic wave filter for receiving the other of the tw o second signals from the balun coupler, converting that into a magnetosatic wave signal, and oppositely converting the magnetostatic wave signal, wherein the received second signal is converted into the magnetostatic wave signal having an energy linear to the power of the input signal; and a power synthesizer for synthesizing the respective signals output from the saturati on magnetostatic wave filter and the linear magnetostatic wave filter. The S/N enhancer does not need phase shifter, and can be applied to a small-sized system that has a broadband and is used at a high power/a low power.
