Getting Ahead with the Interference Task

The new CST^® interference task is a new system-level tool, for the simulation of RF interference and receiver desense. It can be used to analyze inter-systems and intra-system coupling and delivers information about the possible occurrence of RF interference at a glance. The interference task is fully integrated into the CST STUDIO SUITE^®, making it easy to run different scenarios and test mitigation strategies. In this webinar we will present all steps necessary to perform the simulation of RF interference and explain the concepts behind the tool:

• Introduction to the analysis method.
• Definition of a coupling matrix for interference analysis.
• Definition of RF systems from building blocks like receiver and transmitter.
• Analysis of simulation results.
• Advanced source definition using schematic simulation.

In the first part of this webinar, we will demonstrate how a full wave 3D simulation can be used to analyze the coupling between different RF systems, antennas and digital signal lines. The analysis will be performed on a model of a modern, realistic mobile phone with a high complexity. The coupling data will then be used to estimate the possible RF interference using a completely new product: The CST interference tool. In this new system-level tool, RF systems can be defined to analyze inter-system coupling. The analysis delivers the possible occurrence of RF interference at a glance. The interference tool is fully integrated into the CST STUDIO SUITE, making it easy to run different scenarios and test mitigation strategies after the detection of possible interference.
