A Redshift Measurement System for the Large Millimeter Telescope

Erickson，Neala将设计、制造、测试和集成一种全新的毫米波接收器，并将其集成到NSF的NRAO Greenbank望远镜(GBT)和由国防高级研究计划局(DARPA)建造的大型毫米波望远镜(LMT)上。该仪器将测量整个75至110 GHz晴朗大气传输窗口的天文辐射源的辐射，频率分辨率为50 MHz。其独特的技术有：1.单片集成超低噪声放大器和宽带混频器的研制；2.前端中频放大器的研制；3.宽带光谱仪后端的研制。***

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. ***
