Abstract
The present invention provides a frequency converter including a frequency conversion device capable of accommodating a Si-series MMIC and also a GaAs-series MMIC by using a magneto-resistance element. A frequency converter according to an embodiment of the present invention includes: a frequency conversion device having a magneto-resistance element with a magnetization free layer, an intermediate layer, and a magnetization pinned layer; a magnetic field application mechanism for applying a magnetic field to the frequency conversion device; a local oscillator for applying a local oscillation signal to the frequency conversion device; and an input terminal electrically connected to the above frequency conversion device for receiving an external input signal. Further, the local oscillator includes a magneto-resistance element capable of generating the local oscillation signal by outputting an AC voltage according to a resistance change thereof.
