摘要：
We have investigated the theoretical performance of a subharmonically pumped Pb/Bi/In-oxide-Ag superconductor-insulator-normal metal mixer and found excellent receiver noise performance for signal frequencies above the gap frequency, DELTA/h, if the junction is biased at zero volts. This type of mixer needs no pair current suppression and can use local oscillator power more efficiently than a fundamental mixer.
