Abstract
A fixed-tuned SIS mixer covering an instantaneous band of 45% around 150 GHz has been developed for radioastronomy. A new type of coplanar tuning circuit for the SIS junction is introduced. The minimum DSB receiver noise is 19 K, while the average noise is 25K in the 130-175 GHz range with a 1 GHz IF band. A speedup of the observations by a factor 2-3 is possible with the new receiver.
