TUMA9: Low Noise Amplifiers for Cryogenic Applications

Abstract
There is an increasing need for RF low noise amplifiers (LNAs) that operate at cryogenic temperatures. This is largely due to growing demand in quantum computing, deep-space communication, radio astronomy, and low-temperature physics research. These applications require LNAs that can amplify extremely weak signals while contributing negligible added noise to the system. To achieve best-in-class noise performance, beyond that traditionally possible, innovations are being investigated and adopted. This talk will provide an overview of applications, discuss technological advancements that allow this noise performance to be realized, and highlight the exceptionally low noise temperatures being achieved today.
