摘要：
We have recently measured the noise characteristics of two low-noise commercial amplifiers in the 2.0-4.0 GHz frequency range, The tests were part of a program to develop and validate measurement methods for a noise-figure measurement service. Measured noise figures were about 0.5 +/- 0.04 dB, We present the results and the accompanying uncertainties. We also describe the measurement method and summarize the many checks that were used to validate the method.
