Y-FACTOR VS. COLD-SOURCE NOISE MEASUREMENT OF RF/MICROWAVE LNAS
Posted: Monday, August 2, 2021
There are several methods for making noise figure (NF) measurements of RF, microwave, and millimeter-wave low noise amplifiers (LNAs), each with a wide number of options, instruments, and techniques. In a recent Tech Brief, Erzia reviews how we came up with an approach using standard laboratory equipment that can easily be followed by trained personnel working at higher frequencies to obtain optimal NF data.
