The Submillimetre Wave Instrument (SWI) is a spectrometer/radiometer instrument operating in two submillimetre channels around 250 and 530 μm. The SWI measures spectra and continuum emissions in two bands between 530 – 601 GHz.The passively cooled front-end receiver unit developed by Omnisys is based on GaAs Schottky membrane mixer and cryogenic InP HEMT MMIC technology from Chalmers University of Technology.
