Abstract
The ability to manipulate quantum information encoded in microwave fields has led to a renewed interest in Josephson parametric amplifiers (JPAs). For these applications the ability of JPAs to amplify signals with the least amount of added noise is critical. Unfortunately JPAs are typically narrow band amplifiers with small dynamic range. It is therefore important to understand the bandwidth and dynamic range of any particular JPA in order to determine if it is appropriate for these applications. We recently introduced a new kind of JPA. Although it is still narrow band, the amplified band can be tuned over a full octave. We have shown that it has good noise performance and can squeeze the vacuum noise by 10 dB. Here we characterize other important parameters of this amplifier, specifically the signal-bandwidth, dynamic range and saturation power.
