SIS receivers have higher sensitivity than Schottky diode receivers. The SIS mixer, however, must be cooled at 4 K level, and either a GM (Gifford-McMahon) + JT (Joule- Thomson) refrigerator or liquid helium is used. Therefore, SIS receivers are usually much larger and heavier than Schottky diode receivers which are usually cooled by a GM refrigerator only.

Kuriyama et al. developed a GM refrigerator using Er3Ni as a regenerator material which achieved to cool at 4 K level.

In this work, the SIS receiver was constructed and investigated, which was cooled below 4 K by the GM refrigerator with Er3Ni. It resulted in the SIS receiver which was about the same size and weight as a usual Schottky diode receiver.
