RF Power Amplifier Model Extraction for Accurate and Fast Load Pull Simulations with Wideband Signals

This paper presents a novel behavioral model for power amplifiers (PAs) that aims to address the inclusion of both high and low-frequency memory effects as well as load impedance mismatch effects. Through the application of a combined methodology, integrating three-tone characterization with loadpull measurement techniques, the paper attempts to offer a comprehensive modeling of the intricate behaviors of PAs under a large range of operational conditions, including load pull conditions. The proposed model seeks to improve predictive accuracy and support the development of more efficient telecommunications systems by anticipating complex RF system performances. This work aims to provide a robust system simulation framework in the context of the complexity of modern communication signals, which are included in 5 G standards.
