The RF System DesignGuide configures transmitter and receiver chains using behavioral system models. The DesignGuide provides a complete tool kit to interactively explore Transmitter/Receiver systems at the top level as part of an integrated design process. The inherent capability of ADS allows you to replace all the behavioral models with transistor level circuits. The DesignGuide also facilitates design of a transmitter or receiver by incorporating schematics and data displays that have been pre-configured to create, simulate and measure the performance of the system.
You can use the Transmitter/Receiver Topologies templates to define a system configuration, and then proceed to characterize the performance with respect to quantities such as Noise Figure, Carrier-to-Noise Ratio, Carrier-to-Intermodulation Distortion, etc. The final performance measurement is then observed as the given modulation is applied and quantities such as ACPR and EVM are measured. If more sophisticated sources are required, the Co-Simulation Topologies can be used to easily interface with either a user-defined Ptolemy source or one of the available libraries.

The RF System DesignGuide is integrated into the ADS Circuit Envelope Element.
