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
