“Over the years I’ve come to realize that, particularly in signal integrity, half-wave resonances are often the cause of ugly S-parameters. You can argue that any type of resonance would cause problems, and you would be right. However, half-wave resonances are easily formed in topologies.” This article summarizes observations from Gustavo Blando on the formation and mitigation of half-wave resonances, and includes an in-depth study on the topic in PDF format from the author.

SIJ editorial advisory board member Yuriy Shlepnev offers a comparison of three ways to visualize the same s-parameter data, identifying how to get the most information from a plot.

EDI CON Online 2021, an interactive event that was held every Wednesday in August 2021, provided workshops, technical sessions, and keynote talks for engineers working on RF, microwave, EMC/EMI, signal integrity, and power integrity designs.

How well do statistical models predict the behavior of real-world systems?  How can we make predictions about the likeliness and severity of worst-case system behavior?  In this article, the authors explain how they used a function generator and oscilloscope to collect varying population sizes of measurement parameter results in order to investigate the accuracy of a statistical model's predictions.

While eye diagrams and eye masks are both useful, they each hide as much information as they reveal. Read on to see how to get the most out of them for your design.

Bends in PCB traces look like very basic, simple structures that are easy to simulate. Technically, one can do the analysis with any electromagnetic solver with sufficiently accurate port de-embedding capabilities. The reflections from a bend in fine-line, high-speed digital interconnects are relatively small and may not even be detectable with measurement. So, who cares? Read on to find out more.

SIJ recently caught up with Timothy Vang, vice president of marketing and applications for Semtech’s Signal Integrity Products Group about the company’s latest product for 50Gbps PAM4 5G front haul deployments, how signal integrity and RF/wireless design overlap, and what is next for the team at Semtech.

In this tongue-in-cheek experiment that leads to actionable conclusions, Ben Dannan and Steve Sandler set out to discover a method to mitigate the lack of an isolation calibration step on a VNA.

Data usage is increasing every year, and the communications industry is working diligently to support the increased demand. This article discusses why we need more data, what data center physical layer architecture changes are needed to support higher data rates, and how connector manufacturers are improving designs to support higher data rate systems.

DesignCon honors Cathy Liu, engineer and director at Broadcom SerDes Architecture and Modeling Group, as the 2021 winner of its Engineer of the Year award.
