Josephson parametric amplifier with Chebyshev gain profile and high saturation
Ryan Kaufman, Theodore White, Mark I. Dykman +10
We demonstrate a Josephson parametric amplifier design with a band-pass impedance matching network based on a third-order Chebyshev prototype. We measured eight amplifiers operatin…
