White Papers

Designing advanced wireless systems is daunting. Modelithics high-fidelity RF system models, now in PathWave System Design, minimize complexity by providing real-world system simulation. Keysight’s latest White Paper, Highly Accurate RF System Modeling for Wi-Fi and Cellular Interference Analysis, demonstrates how to apply these models in an interference analysis of Wi-Fi and LTE coexistence.

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.

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.

High speed data interfaces like USB, HDBaseT™, HDMI, DVI, and DisplayPort require careful consideration to ensure reliable communication that is free of disruptive EMI. Of the many tools at the designer’s disposal like trace routing, termination and component placement, the common mode filter choke remains one of the most powerful. This application note discusses the benefits of using common mode chokes and reviews the performance characteristics associated with their proper application.

The electro-mechanical method used to attach an RF connector to a coaxial cable is called the “cable termination.” Cable termination methods have evolved over the years to improve assembly performance in demanding applications. Military, space, telecommunications, and test and measurement industries design system upgrades to meet market needs and advancements in technologies.
