Over the past several decades, wireless system channel counts and bandwidths have steadily increased. The driving factors for these modern telecommunication, radar, and instrumentation systems are their data rate and overall system performance requirements. However, these requirements have also increased power envelopes and system complexities, making power density and component level features more important.

This white paper provides in-depth guidance in navigating 5G VoNR from the network deployment and the connectivity options aimed at not only supporting VoNR, but also ensuring the data services that VoNR should enable. A brief summary is also provided on the signaling parameters for both the network and UE side.

While traditional RF and microwave applications are predominantly focused on wireless communication or navigation, recent advances in device technology have opened up an exciting range of non-communication, non-navigation applications of RF and microwave power. Dielectric heating is an important part of any RF and microwave heating process.

The development of Advanced Driver Assistance Systems (ADAS) and the evolution of in-vehicle infotainment devices are transforming automotive design and electronic architecture. This trend has led to more antennas in modern vehicles that require more measurement and verifications to ensure their performance and to analyze the coupling with the car structure. Antenna performance and placement are determining factors in establishing stable and reliable wireless communication between vehicles (V2V), infrastructure (V2I), and networks (V2N). Testing antennas, optimizing subsystems, and evaluating vehicle behavior in real driving conditions are key to developing secure wireless communications systems for tomorrow's vehicles. We invite you to explore our infographic presenting advanced antenna measurement and OTA techniques, OTA tests, V2X and post-processing solutions by MVG.

5G mmWave frequencies have required a new way of testing using over-the-air (OTA) measurements. The first article is an in-depth look at the fundamentals of 5G OTA testing, overview of key antenna measurement parameters, test methods and test setup, along with 3GPP OTA testing for UEs along with the relevant transmitter and receiver test considerations. The remaining articles discuss recent advances in 5G OTA testing ranging from test methods to new chambers and calibration methods. The first article in this group addresses significant test time reduction and equipment utilization in 5G RF production testing through strongly parallelized testing of the 3GPP specifications, improving speed by a factor of 10. The next article reviews the design of a novel multiple compact antenna test range system for multiple angles of arrival measurement of 5G mmWave devices. The virtual cable calibration method is described and demonstrated in the next article that provides a systematic approach with fast convergence to determine the precoding calibration matrix parameters. The last article discusses the future with bringing full-wave numerical modeling and antenna measurements together and presents a way to converge both worlds in an optimal cost-benefit technique moving toward augmented OTA.

TVS diodes help protect electronic circuits from surge voltages associated with an ESD event. XFdtd’s transient EM/circuit co-simulation capability combines the strength of 3D full-wave electromagnetic simulation with the flexibility of circuit solvers. This paper examines the approach, which embeds a transient nonlinear circuit solver in the full-wave simulation so that all electromagnetic phenomena are accounted for in a single time-domain simulation.

This article describes market disruptions currently faced by the space industry which may not only upend current commercial assumptions, but herald significant changes in the way that space-borne infrastructure is architected and operated in future. The hypothesis is that market forces and technology trends point to a necessary focus on substantially more flexible multi-mission platforms hereafter.

When discussing antennas, “impedance matching” commonly appears during the design and final phases. The antenna must be impedance matched when assembled for the end environment so it can operate with maximum efficiency. This process consumes a large amount of time hence it is worth understanding the basics of impedance matching.

The excellent phase noise exhibited in ADI’s latest generation of high speed DACs enables size, weight, power/performance, and cost benefits in next-generation low phase noise, fast hopping agile RF/microwave synthesizers.

This application note offers a straightforward description of how to analyze EMI problems using the Rohde & Schwarz Oscilloscopes. The discussion begins by covering the basic mechanisms that can result in unwanted RF emissions and then describes how to proceed in analyzing EMI problems. Finally, a practical example is given to illustrate the analysis process.
