“…In the high frequency range, the parasitic capacitance C p between the input coil and SQUID loop increases, and this makes the transfer of input flux into SQUID loop difficult. By placing the input coil inside the SQUID hole, the parasitic capacitance can be reduced much, but the multi-turn coil inside the SQUID hole reduces the mutual inductance with the SQUID loop, resulting in reduction of the amplifier gain [3,4].…”

Superconducting quantum interference device (SQUID) is a sensitive detector of magnetic flux signals. Up to now, the main application of SQUIDs has been measurements of magnetic flux signals in the frequency range from near DC to several MHz. Recently, cryogenic low-noise radio-frequency (RF) amplifiers based on DC SQUID are under development aiming to detect RF signals with sensitivity approaching quantum limit. In this paper, we review the recent progress of cryogenic low-noise RF amplifiers based on SQUID technology.

“…Exlernal RF pump influence on DC SauID I-V curve We studied experimentally the influence of external microwave irradiation at irequencies of i6, 26 and 75 GHz on I-V curves of integrated four-loop DC SQUIDS(Tarasov et al 1991).Figure 1shows typical curves for different values of magnetic flux caused by input coil current bias. I-V curves of DCSOUID with external irradiation at 16 GHz (a), 36 GHz (6) and 75 GHz (c).…”

The power gain and the noise temperature of a DC SQUID RF amplifier at a signal frequency 400 MHz were measured in the presence of external microwave radiation at 2 cm, 8 mm and 4 mm wavelengths. The authors used a four-loop planar DC SQUID with an integrated input coil and very low values of inductances and stray capacitances. In the noise measurements they used an SIS junction as a precise source of input noise at high DC bias voltage Vb>V2 Delta . In such a configuration the studied system is the same as an SIS mm-wave mixer with a SQUID IF amplifier.
