Abstract
A frequency converter includes: a plurality of mixers each including a magnetoresistance effect device including a fixed magnetic layer, a free magnetic layer, and a nonmagnetic spacer layer sandwiched between the fixed magnetic layer and the free magnetic layer, when receiving a first high-frequency signal and a local second high-frequency signal, the magnetoresistance effect device multiplying the first high-frequency signal and the local second high-frequency signal by a magnetoresistance effect to generate a multiplication signal, and a magnetic field applying unit that applies a magnetic field to the free magnetic layer. A plurality of multiplication signals generated when the first high-frequency signal and the local second high-frequency signals that differ from one mixer to another are input to the mixers, are added together and are output.
