Abstract
For interstellar spectral line observations in the mm- and submm-wavelength range, low-noise, broadband heterodyne receivers are needed. Using a Niobium-Aluminum Oxide-Niobium SIS mixer element with a broadband integrated tuning circuit in a single-backshort waveguide mixer, we achieved a receiver noise temperature <=100K DSB from 225-255GHz without any backshort tuning. The lowest noise temperature with optimized backshort is 58K DSB at 230GHz with a mixer noise contribution of 27K.
