Abstract
Analytical predictions of additive noise in combined amplifiers and their experimental verification are presented. The analysis addresses both random and deterministic noise processes, and in each case the signal-to-noise ratio of combined amplifiers is compared to that of an individual amplifier inside the combiner. The signal-to-noise ratio of combined amplifiers improves for uncorrelated random noise, but remains unchanged for all other types, including noise figure.
