This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This project is for the design and construction of a sideband-separating Superconductor-Insulator-Superconductor mixer receiver for the 380 to 500 GHz band. The receiver, whose design will mimic that used for the Atacama Large Millimeter/submillimeter Array (ALMA) 210 to 275 GHz receiver developed by the National Radio Astronomy Observatory, would be deployed on the Arizona Radio Observatory's Sub-Millimeter Telescope on Mt. Graham, Arizona. The receiver would be used to study known molecular spectral lines in this region, as well as likely discover many new ones. The advantage of this design over the ALMA design is that the balanced system allows the use of much lower local oscillator power, which can be important in some instances (such as array feeds, for example) where sufficient local oscillator power is difficult to achieve.

该奖项由2009年美国复苏和再投资法案（公法111-5）资助。该项目旨在设计和建造380至500 GHz频段的边带分离超导体-绝缘体-超导体混频器接收机。该接收器的设计将模仿国家射电天文台开发的阿塔卡马大型毫米/亚毫米阵列（阿尔马）210至275 GHz接收器，将部署在亚利桑那州射电天文台的亚毫米望远镜上。格雷厄姆，亚利桑那州。该接收器将用于研究该地区已知的分子谱线，并可能发现许多新的谱线。这种设计优于阿尔马设计的优点在于，平衡系统允许使用低得多的本地振荡器功率，这在难以实现足够的本地振荡器功率的某些情况下（例如阵列馈电）可能是重要的。
