Nonlinear Modeling

Nonlinear elements, nonlinear behavior, intermodulation distortion, IP2/IP3, interference

Use these blocks to specify the nonlinear behavior of amplifiers and mixers. Such behavior includes IP2/IP3, intermodulation distortion and 1 dB compression. You can also simulate frequency-dependent mismatches between components.
