RF Budget Analysis

Calculate power, gain, noise, and intermodulation budget for RF cascade elements

You can perform budget analysis of RF networks using the RF Budget Analyzer app or an rfbudget object. You can subsequently perform full circuit envelope or time domain simulation using an rfsystem System object™.


RF Budget AnalyzerAnalyze gain, noise figure, IP2, and IP3 of cascaded RF elements and export to RF Blockset
