Antenna Impedance Matching Simplified

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.

Low Phase Noise DAC-Based Frequency Synthesis for Fast Hopping Wideband Microwave Applications

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.

EMI Debugging with Oscilloscopes

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.

Featured Application Note: Selecting Common Mode Filter Chokes for High Speed Data Interfaces

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.

Overcoming Miniaturized Routing Challenges with Solderless Terminations

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.
