A Redshift Measurement System for the Large Millimeter Telescope

一种全新的毫米波接收器将被设计、建造、测试并集成到NSF的NRAO Greenbank望远镜（GBT）和美国国防高级研究计划局（DARPA）正在建造的大型毫米波望远镜（LMT）上。该仪器将以50兆赫的频率分辨率测量整个75至110千兆赫清晰大气传输窗口内的天文源辐射。 独特的技术是1。单片集成超低噪声放大器和宽带混频器的研制。中频放大器在前端，3。宽带光谱仪后端。***

AST-0096854Erickson, NealA fundamentally new kind of millimeter-wave receiver will be designed, built, tested and integrated onto the NRAO Greenbank telescope (GBT) of NSF and onto the Large Millimeter Telescope (LMT) being built by the Defense Advanced Research Projects Agency (DARPA). The instrument will measure radiation from astronomical sources across the entire 75 to 110 GHz window of clear atmospheric transmission with 50 MHz of frequency resolution. The unique technologies are 1. The development of monolithic integrated ultra-low noise amplifiers and wideband mixers, 2. Intermediate frequency amplifiers in the front end, 3. A wideband spectrometer backend. ***
