Celestial Signals: Are Low-Noise Amplifiers the Future for Millimeter-Wave Radio Astronomy Receivers?


Radio emission emanating from celestial sources was first detected by Karl Jansky during the 1930s. Using primitive radio instrumentation coupled to a relatively small aperture telescope, Jansky mapped portions of the Milky Way and established the field of radio astronomy. Thus was born a branch of modern astrophysics that has allowed the study of radio emission from cosmic sources and revolutionized our understanding of the universe.
