TUMA14: A Practical Simulation Approach for RF Desense Mitigation of Consumer Electronics

Abstract
The Internet of Things (IoT) demand smaller device footprints with greater functionality. As data rates and communication ranges rise, interference between co-located digital and RF systems becomes a major development risk. Simulation is common in electronics design, yet expectations can be unrealistic and models overly complex. When applied effectively, however, simulation reveals risks and guides mitigation. This talk demonstrates a workflow combining physics-based field solvers with behavioral system models for efficient characterization of mixed-signal electronics. FEM determines transfer functions and interference paths, spectra are derived analytically or by Fourier transform, and final performance models enable isolation and spectral-management strategies.
