Fabrication of the Impedance-Matched Josephson Parametric Amplifier and the Study of the Gain Profile
Fabrication of the Impedance-Matched Josephson Parametric Amplifier and the Study of the Gain Profile
We designed and fabricated an impedance matched Josephson junction parametric amplifier (JPA) working in the flux-pump mode for the broadband amplification of microwave signals. We developed a very simple fabrication method suitable for a small lab. We studied the phase response, as well as the gain, as a function of …
