DC Squid as a tuned radiofrequency amplifier

Conference · · IEEE Trans. Magn.; (United States)
OSTI ID:6340998

The design criteria for a tuned radiofrequency amplifier based on a dc SQUID are briefly discussed. A practical amplifier involving a planar dc SQUID with a 4-1/4-turn spiral input coil and operated at 4.2K had a gain of 18.6 + or - 0.5 dB and a noise temperature of 1.7 + or 0.5K at 93 MHz. These results are in satisfactory agreement with predicted values.
