    • A frequency converter, capable of obtaining resonance characteristics having a high Q factor and a high multiplication signal and having a narrow-band frequency selectivity function, is provided by the following configuration. A magnetoresistance effect element includes a pinned magnetization layer, a free magnetization layer, and a non-magnetic spacer layer disposed between the pinned magnetization layer and the free magnetization layer. In response to an input of a high frequency signal and a local signal, the magnetoresistance effect element generates a voltage signal (multiplication signal) by multiplying the signals by each other using a magnetoresistance effect. A magnetic field generated by a magnetic-field applying unit is applied to the free magnetization layer of the magnetoresistance effect element in a direction perpendicular to a film surface direction or by tilting an angle of the magnetic field from the film surface direction toward a direction perpendicular to the film surface direction.
    • 通过以下配置提供能够获得具有高Q因子和高乘法信号并具有窄带频率选择性功能的谐振特性的变频器。 磁阻效应元件包括钉扎磁化层,自由磁化层和设置在钉扎磁化层和自由磁化层之间的非磁性间隔层。 响应于高频信号和本地信号的输入,磁阻效应元件通过使用磁阻效应将信号彼此相乘产生电压信号(乘法信号)。 由磁场施加单元产生的磁场在垂直于膜表面方向的方向上施加到磁阻效应元件的自由磁化层上,或者通过使磁场从膜表面方向的角度向垂直方向倾斜 到膜表面方向。
