本文提出了详细的实验和分析结果的500 GHz的无调谐波导SIS混频器，这是与并联连接的双结。500 GHz SIS混频器表现出低的整体接收机噪声温度为176 K，在482 GHz，尽管相对较差的SIS结的质量。因此，结子间隙泄漏的影响进行了研究。最后将实验结果与量子混合理论模拟的结果进行了比较。
This paper presents detailed experimental and analytical results for a 500-GHz tuneless waveguide SIS mixer, which is incorporated with parallel-connected twin junctions. The 500-GHz SIS mixer exhibits as low an overall receiver noise temperature as 176 K at 482 GHz, despite relatively poor quality of the SIS junction. The effect of the junction subgap leakage is therefore investigated. The experimental results are finally compared to those simulated by the quantum theory of mixing.
