Intermodulation Products for a Mixer Subjected to a Multi-carrier Signal

Use of a nonlinear mixer model to demonstrate how a transient simulation is used to predict the behavior of intermodulation products in a multi-carrier environment
Technical Feature Intermodulation Products for a Mixer Subjected to a Multi-carrier Signal Applying a multi-carrier signal to a mixer leads to a large range of intermodulation products. To perform a link budget of a multi-carrier transmit-receive system, it is important to predict the location and magnitude of those intermodulation...
