Noise figure is routinely used by system and design engineers to ensure optimal signal performance. However, the use of mixers in the signal chain creates challenges with straightforward noise-figure ...

The noise figure of semiconductor devices used in devices such as TV tuners and cell phones are a critical factor in determining the sensitivity and performance of this equipment. The National ...

This application note describes in detail the steps required to make a noise figure measurement on a spectrum analyzer using the “Y Factor” technique. July 2, 2025 This application note describes in ...

RF-to-baseband front ends consisting of a low-noise amplifier (LNA) cascaded with a mixer downconverting RF signals to baseband have become the epitome of RF devices tested in high-volume ...

If you’re planning on working satellites or doing any sort of RF work where the signal lives down in the dirt, you’re going to need a low-noise amplifier. That’s typically not a problem, as the market ...

This tutorial starts by examining the fundamental definition of noise figure and continues with an equation-based analysis of cascade blocks involving mixers, followed by typical lab techniques for ...
