Noise figure is a critical performance parameter that defines radio receiver component performance. Accurate measurements of noise figure let you select components and optimize receive chain tradeoffs ...

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 ...

Modern digital receiver/exciters (DREX) used in radar and communications systems are capable of significant self-testing in a production factory environment. Long past are the days where the analog ...

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 ...

The thermal noise of the electric current has been well known for almost a century. In an article published this week in Physical Review Letters, a group of researchers from the Low Temperature ...
