对高频本振驱动的超导准粒子非线性传输线的行为进行了分析。该理论包括大信号非线性分析、小信号分析和噪声分析。利用该模型模拟了基于非线性传输线的分布式准粒子混合器的转换损耗和噪声温度。数值结果与460 GHz实验混频器进行了比较。该理论还预测，非线性传输线将提供参数放大时，空转频率的感应调谐。这种新现象可能为亚毫米波长的低噪声接收系统提供新的机会。
An analysis is presented for the behavior of the superconducting quasi-particle nonlinear transmission line driven by a high-frequency local oscillator (LO). The theory developed includes a large-signal nonlinear analysis, a small-signal analysis, and a noise analysis. This model is used to simulate the conversion loss and noise temperature of distributed quasi-particle mixers based on the nonlinear transmission line. The numerical results are compared to an experimental mixer at 460 GHz. The theory also predicts that the nonlinear transmission line will provide parametric amplification when the idler frequency is inductively tuned. This new phenomenon may present new opportunities to low-noise receiver systems at submillimeter wavelengths.
