Noise Figure is a key figure of merit particularly in RF design. The noise figure is defined as the signal to noise ratio of the signal entering the device divided by the signal to noise ratio of the signal exiting the device. Noise figure is often communicated in log scale or decibels, since this makes many calculations easier. When multiple devices are cascaded, the overall “Cascaded Noise Figure” of that circuit may also be calculated.
Triad employs many circuit techniques to deliver industry leading low noise solutions to our customers. Our engineers understand what contributes to a device’s noise figure and how to optimize it for the application.
