Abstract :
Attention is directed to the signal reflection gain and the signal-to-image conversion gain in the quantum theory of mixing. The theory gives two distinct types of solutions for the minimum noise temperature of an SIS (superconductor-insulator-superconductor) receiver. One has very high IF (intermediate frequency) conversion gain, and the returned signal and image powers are extremely high as well. The other has moderate IF conversion gain, but the returned powers tend to be very small.<>
