Noise Modeling

Noise sources, phase noise, thermal noise, noise figure specification

Use noise sources to simulate white or colored noise in RF models and calculate the noise power. To calculate thermal noise, use S-Parameters block.

Model System Noise Figure

RF receivers amplify signals and shift them to lower frequencies.

Designing a Receiver with an ADC

Most RF receivers in modern communications or radar systems feed signals to an analog-to-digital converter (ADC).

Noise in RF Systems

Noise factor, noise figure, noise floor, thermal noise power, noise temperature, white noise, colored noise.
