Abstract:
1. A mixer comprising: a magnetoresistive effect element that includes a fixed magnetic layer, a free magnetic layer, and a nonmagnetic spacer layer disposed between the fixed magnetic layer and the free magnetic layer, is operable when a first high-frequency signal and a second high-frequency signal as a local signal are inputted, to multiply the first high-frequency signal and the second high-frequency signal according to a magnetoresistive effect to generate a multiplication signal; a magnetic field applying unit that applies a magnetic field to the free magnetic layer; and an impedance circuit that has a higher impedance for the multiplication signal than an impedance for the first high-frequency signal and the second high-frequency signal and is disposed between an input transfer line, which transfers the first high-frequency signal and the second high-frequency signal, and the magnetoresistive effect element.
