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.
A classic superheterodyne architecture filters images prior to frequency conversion.
This example shows how to use the RF Blockset™ Circuit Envelope library to calculate the image rejection ratio (IRR) for high-side-injection in Weaver and Hartley receivers.
