The design and performance of a 210 - 280 GHz SIS heterodyne receiver built for use on the Maxwell Telescope are described. The mixer utilizes a lead alloy SIS tunnel junction mounted in 4 to 1 reduced height rectangular waveguide, and is tuned with a backshort in 2 to 1 reduced height guide. The receiver has a receiver noise temperature of less than 200 K (DSB) across the RF band from 210 - 270 GHz with a best noise temperature measured in the laboratory of 113 K (DSB) at 231 GHz. A prototype version of this receiver was successfully operated on the telescope in May 1989. By direct intercalibration with a Schottky diode receiver a best receiver noise temperature of 140 K (DSB) at 245 GHz is deduced.
