摘　　要：用介质谐振器作带阻滤波器制作毫米波镜像回收混频器 .在理论分析的基础上 ,给出了实际电路 .实验结果表明 ,用介质谐振器制成的镜像回收混频器 ,在信号口可以使变频损耗减小约 1.1d B,并具有 2 6 dThe 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.
