点击翻译按钮获取中文摘要

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. ***
