Abstract：
The invention discloses a harmonic wave inhibition frequency mixer, and relates to the technical field of wireless communication. According to the invention, two second orthogonal current type frequency mixers are arranged, only one of the two orthogonal current type frequency mixers works in the same period, the problem of phase uncertainties is solved by use of a mode of switching the work states of the two orthogonal current type frequency mixers, accurate matching between phases and gains is realized, and the harmonic wave inhibition ratio is improved.
