All mixers use SRON junctions.
Note that since only one local oscillator is provided, both mixers observe the same frequency range. The tuning range at C-band is from about 430 to 510 GHz, and that for D band about 620 to 710 GHz. The atmospheric window covered by the C-band is shown here . The atmospheric transmission for a pwv of 0.5mm is shown together with the positions of a selection of spectral lines likely to be of interest. Over much of the C-band the SSB receiver temperature is around 330 K or possibly better.
