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 rfbudget object.

RF Budget Harmonic Balance Analysis of Low-IF Receiver, IP2 and NF

RF Budget Harmonic Balance Analysis of Low-IF Receiver, IP2 and NF

Use the rfbudget object's harmonic balance solver to analyze a low-IF (intermediate frequency) receiver RF budget for second-order intercept point (IP2), the second-order intercept point and to compute a more accurate noise figure (NF) that correctly accounts for system nonlinearity and noise-folding.
