PROBLEM TO BE SOLVED: To provide a spin high-frequency mixer capable of having improved noise characteristics, and to provide a method of manufacture thereof. SOLUTION: A spin high-frequency mixer includes: a spin current generator 30 generating a spin current upon input of a local oscillator signal; a TMR (tunnel magnetoresistance effect) device 50 which inputs a high-frequency signal and the spin current generated by the spin current generator 30 and generates a mixed signal; and an output device 60 outputting the generated mixed signal from the TMR device. Generation of shot noise at a passive mixer is suppressed almost without including shot noise caused by a current of the local oscillator signal. COPYRIGHT: (C)2010,JPO&INPIT
