To calculate cascaded noise figure and gain, you can use the rfbudget function over an ordered array of RF Toolbox elements. It computes transducer gain, noise figure, SNR, and output power across the RF signal chain.

The Friis solver provides fast linear budgeting, while the HarmonicBalance solver delivers more nonlinear-accurate results. HarmonicBalance is used for analyzing compression and intermodulation behavior in the RF cascade.

You can plot RF budget results by using the rfplot function to inspect cascaded metrics. Additionally, the show function displays the results, allowing you to visualize stage-by-stage performance.

Yes, rfbudget supports export-ready workflows to MATLAB scripts, RF Blockset, or Communications Toolbox. This allows you to configure receivers and transmitters directly from the budget analysis.

You need an ordered element array of RF Toolbox components, an input frequency, available input power, and signal bandwidth. These inputs satisfy the solver contract for calculating system performance.

Use HarmonicBalance when you need nonlinear accuracy, such as analyzing compression or intermodulation behavior. Friis is better suited for fast, linear RF link budgeting across the cascade.
