Субмиллиметровый приемник с монолитным балансным смесителем

We describe the design of the superheterodyne receiver with balance monolithic integrated mixer, as well as the technique and results of measurements of the receiver and mixer parameters in frequency range 287-365 GHz. In the middle of this range, double sideband noise temperature of the receiver is equal to (1500+50) K, while mixer double sideband noise temperature and conversion loss equal (1250+50) K and (10+0.5) dB, respectively. The comparison with mixer and receivers of other types is made.
