MILLIMETER WAVE MIXER WITH IMAGE RECOVERY USING DIELECTRIC RESONATORS
【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 d B以上的镜像抑制比
【Abstract】 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.
