采用量子混频器理论的三端口近似来对具有集成调谐结构的 SIS 结点在 230 GHz 下执行混频器增益计算。此外，波导混频器安装座的嵌入阻抗范围已从模型测量中获得，并已包含在增益计算中。结果表明，当使用集成调谐结构时，即使是相当小的结也可以在波导环境中表现良好。提出了一种三元件调谐电路，该电路允许以固定嵌入阻抗进行宽带操作，这对于使用平面天线结构的应用非常重要。
A three-port approximation of the quantum mixer theory is employed to perform mixer gain calculations at 230 GHz for SIS junctions with integrated tuning structures. In addition, the embedding impedance range of a waveguide mixer mount has been obtained from model measurements and has been included in the gain calculations. The results show that even moderately small junctions can perform well in a waveguide environment when an integrated tuning structure is used. A three-element tuning circuit is presented that would allow broad band operation with a fixed embedding impedance which is important for applications using a planar antenna structure.
