Abstract
This article reports on the evolution in designing state-of-the-art cryogenic, wideband, low-noise amplifiers as used in the intermediate frequency stages of ALMA receivers. The most recent designs are presented which demonstrate exceptional bandwidth and noise performance; those are crucial in enabling the planned ALMA Wideband Sensitivity Upgrade.
