Markus Loerner Marketing Expert Markus Loerner is a marketing expert at Rohde & Schwarz focusing on the RF & microwave component market. He joined Rohde & Schwarz in 2000 and worked as a signal generator product manager in various RF applications from mobile wireless to satellite communications, for both R&D and production use. He holds a degree in electrical engineering from the University Erlangen-Nuremberg, Germany.

From Design to Real RF Device - Connecting EDA Simulation and Hardware Test

In partnership with Rohde & Schwarz

Streamlining the development process of RF components and systems as well as risk management in the development process are the goals of bringing simulation and hardware verification closer together. Simulation with complex wideband signals according to latest 5G NR or Wi-Fi specifications allows more realistic results than before. Using the same signal creation methods and analysis algorithms as for subsequent hardware tests ensures a direct correlation from early design to implementation verification.
The R&S®VSESIM-VSS solution is enhancing the capabilities of the Cadence® Visual System Simulator™ (VSS), widely used to perform EDA simulation.

Although RF frontends are highly non-linear when they are operated close to saturation for best energy efficiency, the new method we are introducing gives insights into capabilities and improvement using linearization to enable low signal distortion of the complete RF chain. R&S®VSESIM-VSS supports signal creation and analysis according to the latest 5G and Wi-Fi specifications; combining realistic standard-compliant signal performance investigation with linearization from the R&S VSE Direct DPD method shows what is possible in terms of signal purity and EVM.
