Topic: Investigate RF power amplifier linearization benefits in EDA – including a comparison to hardware test

This webinar is intended for engineers who design RF frontends and RF power amplifiers and strive for the best possible error vector magnitude (EVM) performance.

We will introduce a new joint solution for linearization developed together with Cadence. The solution is based on the R&S®VSESIM-VSS solution which already enhances the capabilities of the Cadence® Visual System Simulator™ (VSS). Additional system level performance insights are now available long before you have hardware available, using the extensive EDA simulation capabilities.

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.

This webinar will include a demonstration in VSS related to real hardware as we compare linearization in the design tool VSS with the actual performance of the device tested with trusted R&S test and measurement instruments.
