Design, Implementation, and Testing of the <i>Microwave Anisotropy Probe</i> Radiometers
The Microwave Anisotropy Probe (MAP) satellite, launched 2001 June 30, will produce full sky maps of the cosmic microwave background radiation in five frequency bands spanning 20-106 GHz. MAP contains 20 differential radiometers built with High Electron Mobility Transistor (HEMT) amplifiers with passively cooled input stages. The design and test …
