When designing circuit boards, a change made to one aspect of the design intended to resolve an issue can cause problems elsewhere. To reduce the problem of soldering on SMA connectors in an edge launch, a significant signal integrity problem has been introduced. This article explores best practices and provides insight into avoiding an inadvertent mistake.

In this article, Donald Telian explains why discontinuities do not sum the same way as loss. Telian outlines that a failing an RL mask might indicate that Tx or Rx are simply too close to a discontinuity, causing the discontinuity proximity effect. Read on to learn more about how to to distance SerDes from discontinuities.

In preparation for 224 Gb/s and beyond, Samtec engaged in a research project to characterize the transmission performance of emerging PCB material sets. Brandon Gore explores the current state of the art for PCBs and cables, comparing them and assessing the technology gap to fully support the insertion loss performance required for higher data rates.

This article presents a quick and easy simulation model for filter performance analysis. The simulation model that the author built matches the test results quite well and it can serve as a useful and powerful tool for electronics design engineers.

Uniform transmission lines are best suited for high-speed data transmission because of their broadband impedance characteristics. In some applications, a minor deviation from uniformity can help in optimizing other desired signal integrity metrics. This paper addresses some of the challenges involved with this approach.
