RF Design TrainingRF DESIGN TRAINING Grenoble - Friday March 30 th Maryvonne Cornelie [Corporate Package Development] Yvon Imbs [TPA/Operations/Back-End Engineering] Why is electrical modeling of packages needed? Integrated RF functions used in wireless applications cover a wide bandwidth leading to high frequency signals (2GHz, 4GHz, 5GHz, etc.) . At these frequencies, electromagnetic interferences are non neglectible. Modeling is used to integrate these effects in simulations. In high speed digital: The package is the main source of noise (SSN). In RF functions: It is need to integrate the parasitics of the package at the beginning of the design (ampli adaptation, impedances matches). Cross-talk modeling help to choose the best leads to carry critical signals. Maryvonne Cornelie [Corporate Package ……
