Characterizing cryogenic amplifiers with a matched temperature-variable noise source
arXiv:2009.03010 · doi:10.1063/5.0028951
Abstract
We present a cryogenic microwave noise source with a characteristic impedance of 50 , which can be installed in a coaxial line of a cryostat. The bath temperature of the noise source is continuously variable between 0.1 K and 5 K without causing significant back-action heating on the sample space. As a proof-of-concept experiment, we perform Y-factor measurements of an amplifier cascade that includes a traveling wave parametric amplifier and a commercial high electron mobility transistor amplifier. We observe system noise temperatures as low as mK at 5.7 GHz corresponding to excess photons. The system we present has immediate applications in the validation of solid-state qubit readout lines.
