一个345 GHz超导体-绝缘体-超导体（SIS）隧道结接收机采用了一个全高矩形波导混频器，并安装在位于夏威夷莫纳克亚山的加州理工学院亚毫米波天文台10米天线上。在设计中心频率为345 GHz，环境温度约为3.8K时，接收机的最佳双边带噪声温度响应为150 K ± 20 K（在中心频率为1.5GHz的500 MHz中频带宽上平均）。附加的测量表明，接收机在280至363 GHz的RF输入范围内的选定点处具有优异的响应。
A 345GHz superconductor insulator superconductor (SIS) tunnel junction receiver utilizing a full height rectangular waveguide mixer with two tuning elements, i.e. an E-plane and backshort tuner, has been constructed and installed on the Caltech Submillimeter Observatory 10m antenna on Mauna Kea, Hawaii. The receiver exhibits a best double side-band noise temperature response of 150K±20K (averaged over a 500 MHz IF bandwidth centered at 1.5GHz) at a design center frequency of 345GHz and at an ambient temperature of approximately 3.8K. Additional measurements show that the receiver has an excellent response at selected points within an RF input range of 280 to 363GHz.
