Advanced Amplifier Based Receiver Front Ends for Submillimeter-Wave-Sounders
Project Introduction
Develop high electron mobility transistor (HEMT) amplifier based heterodyne radiometers to provide high sensitivity at millimeter and submillimeter wavelengths with high spectral resolution for molecular line detection.
Performance goals are:
Low system noise temperature:
< 280K Single Sideband at 230 GHz
< 650K Single Sideband at 640 GHz
Wide spectral coverage:
180-270 GHz (for tropospheric measurements)
620-660 GHz (stratospheric measurements)
Sideband separation: > 15 dB
Amplifier front-end operating temperature: 20K
