Cryogenic mixers in the short-wave part of the millimeter range
Abstract
An investigation was made of the effect of cooling down to 80 K on the characteristics of diode structures intended for millimeter-range mixers. It is shown that, in the best samples tested, the noise temperature can be lowered by 1.5-2 times. Conversion losses of 6.5-7.0 dB were obtained for the structures studied in the mixing mode at frequencies of 80-85 GHz. Attention is given to the possibility of reducing the noise temperature of this type of mixer by 2-3 times in the one-band mode through cooling down to cryogenic temperatures.
