我们报道了在73.5 GHz下SIS与Pb（In）结阵列的混合。阵列几何形状和天线耦合可以用现有技术扩展到300 GHz。测量到的SSB转换损耗为2.0±0.9 dB。这是迄今为止发表的无图像抑制的阻性混频器的最佳转换结果，并且与混合的量子理论非常吻合。我们研究了约瑟夫森效应噪声，从而给出了单结SIS混频器的大致频率上限。
We report SIS mixing with Pb(In) junction arrays at 73.5 GHz. The array geometry and antenna coupling can be scaled to 300 GHz with existing technology. The measured SSB conversion loss is as good as 2.0±0.9 dB. This is marginally the best conversion result for a resistive mixer without image rejection yet published and agrees well with the quantum theory of mixing. We examine Josephson effect noise and thereby give a rough upper frequency limit for single-junction SIS mixers.
