Keysight Technologies High-Accuracy Noise Figure Measurements Using the PNA-X Series Network Analyzer

Keysight Technologies The Communication System Architect’s Guide to 5G Physical Layer Modeling

This paper describes how to model and evaluate a next generation communication system in combined multi-domain simulation environments. Because the communication system consists of complex analog and digital components, it is vital to model accurately in order to understand the behavior of the system. The multi-antenna system architectures, advanced modem technology and millimeter wave (mm-wave...

Keysight Technologies Simulation and Measurement-based X-parameter Models for Power Amplifiers with Envelope Tracking

Static X-parameter (XP) models for RF power amplifiers (PAs), derived from both simulations and nonlinear vector network analyzer (NVNA) measurements, are investigated for the prediction of PA performance under dynamic signal conditions such as in envelope tracking (ET). The instantaneous AM-AM, AM-PM and PAE predictions of XP models extracted from simulation are compared under ET dynamic signa...
