| Popis: | We describe the design and performance of a 210–280 GHz SIS heterodyne receiver built for use on the Maxwell Telescope. The mixer utilises a lead alloy SIS tunnel junction, mounted in 4∶1 reduced height rectangular waveguide, and is tuned with a backshort in 2∶1 reduced height guide. The receiver has a receiver noise temperature of |
