Nettet30. jun. 2014 · The use of a point contact Josephson junction as a parametric amplifier was studied at 9 GHz. The junction used in the experiments was a two-hole RF-biased SQUID (Superconducting Quantum Interference Device) and the pump frequency was close to the signal frequency. The total gain achieved was 10 dB with a bandwidth of 3 … Nettet3. Josephson Parametric Amplifiers The first experimental realization of an AC-pumped Josephson parametric amplifier (ACPJPA) was reported in 1967 by H. Zimmer [14]. This ACPJPA consisted of a thin-film Josephson junction evaporated on a rutile resonator and was operated at 9646 MHz in the double-degenerate mode.
