Abstract
Design details are given for a 205-270 GHz fixed-tuned SIS receiver in which the SIS mixer and HEMT IF amplifier are integrated into a singl e compact unit, The mixer and IF amplifier are connected with an induc tor which provides the reactive part of the optimum input impedance fo r the HEMT. This simple coupling circuit gives an IF bandwidth of simi lar to 4 GHz. The receiver has a DSB noise temperature in the range 35 -80K over the 205-270 GHz local oscillator band and 0.5-4.5 GHz IF ban d.
