IWWE2: Design and optimization of beamforming radios: live demos on how modelling, simulation and OTA measurements can benefit from each other

Presentation Abstract
This workshop explores the synergy between over-the-air (OTA) measurements and modelling/simulation for optimizing wideband mmWave radios. Practical examples will show how to enhance RF models for transceivers design and optimization, covering: • Linearization of power amplifiers and beamforming transmitters • Equalization and interference mitigation strategies for receivers • Leveraging simulation to interpret OTA measurement results. Attendees will learn to improve design, reduce re-spins, and understand root causes of performance issues. The demonstrations will use a highly integrated mmWave beam-former capable of circular polarization, including frequency converters, filters, and a SATCOM phased array in two remote compact antenna test range systems.
