The millimeter wave mixer with image recovery was presented, which used dielectric resonators at Ka band as the band rejection filter. The real circuit was also presented based on the theoretical analysis. The results show that the signal conversion loss is reduced by about 1.1dB, and the image to signal conversion loss ratio is larger than 26dB by using the millimeter wave mixer image recovery.
