Samtec recently published a major white paper, “Wideband RF Launches: Much More Than Footprints On PCBs.” This white paper shows that very wide bandwidth RF launches are possible to implement in PCBs, even with vias included. This does not mean it is a trivial task. Competing requirements, be they electrical, mechanical, manufacturing, or cost, must be considered and balanced simultaneously. This white paper -- a link to it is at the end of this blog -- elaborates on some of … [Read more...]
Samtec SI Technologists to Present at EDI CON Online 2022
"I'm lovin' it." "Can you hear me now?" "Just do it." "Where High Frequency Meets High Speed" The first three taglines are a part of pop culture lexicon. The last describes an annual technology event - EDICON Online 2022 - focused on training and informing engineers on that latest high-performance technologies, solutions, trends and design techniques. The world of high-frequency and high-speed is converging as never before. Real-world and modeled 224 Gbps PAMx system design … [Read more...]
Maximizing RF Launch Performance: The Impact Of GND Vias
(This is the third in a series of blogs, from Sandeep Sankararaman, Samtec’s Principal RF and Signal Integrity Engineer, discussing design strategies for high-bandwidth RF launches. The first is entitled “What Is An RF Connector Launch?” The second is "Via Stubs: Practical Strategies To Mitigate Return Loss.") A wide bandwidth RF launch requires a good ground ring structure around the signal via to maintain the impedance while the signal travels down the via. Figure 1 shows the ground ring … [Read more...]
Via Stubs: Practical Strategies To Mitigate Return Loss
(This is the second in a series of blogs, from Sandeep Sankararaman, Samtec’s Principal RF and Signal Integrity Engineer, discussing design strategies for high-bandwidth RF launches. The first is entitled "What Is An RF Connector Launch?" The third is "Maximizing RF Launch Performance: The Impact of GND Vias." coming next week, discusses GND rings.) When using a through via to transition to an internal layer, there is a stub created by the part of the via that extends below the transition … [Read more...]
What is an RF Launch?
As signal speeds increase, each part of the signal path getting to and from the device needs to work to higher frequencies. Strategies that worked in the past no longer suffice and cheaper connectors no longer make the cut. Cable lengths and trace lengths need to get shorter to reduce losses. This makes intuitive sense. However, what needs to be done with connectors to get them to perform better is not as straightforward. The selection and implementation of RF PCB … [Read more...]
New Cable System Improves Thermal Management and Extends Signal Reach
A new high-speed, high-density Samtec Flyover® cable system extends signal reach to achieve next-gen speeds and improves thermal management. Andy Shrout, Samtec’s High-Speed Cable Product Manager, walks us through this demonstration, originally shown at DesignCon 2022. High-speed channels route directly off the chip package substrate to the front panel, through Samtec Eye Speed® Ultra-Low Skew Twinax. The channels don’t route through BGAs and multi-layer PCBs. This demo also shows how … [Read more...]
Wideband RF Launches: Literally, Everything You Need To Know
As the demand for higher frequencies and wider bandwidths continue their relentless march upward, RF connectors need to keep up and even exceed this demand. Mating the RF connector to a PCB or substrate requires careful consideration of several factors to get the full performance out of the connector. Let’s frame this concept by starting with a simple analogy: Putting tractor tires on a race car is not a recipe for success. Tires on a race car need to convert power from the engine … [Read more...]
Overcoming The Challenges of Achieving 224 Gbps Performance
In this video from DesignCon 2022, Keysight's Mike Resso refers to 224 Gbps as a "blindingly fast speed." Ten years from now, when 224 is old-hat and commonplace, we will look back at that statement and smile at how far we've come since those technologically backward, archaic days of 2022. But as of today, achieving that data rate is bleeding-edge and state-of-the-art. This video, with Mike and Samtec's Jignesh Shah, discusses several topics related to 224 Gbps performance, including ... … [Read more...]
Linear Direct Drive Proof-of-Concept Can Support 100 G+ Signaling
This video from DesignCon 2022 shows a proof-of-concept for an on-package, or near-package, direct-drive electrical channel that can support 100 G + signaling. These drives could be used in mid-board optical and copper designs using Samtec Flyover® cable assemblies or mezzanine connector sets, or for full-channel front-panel and back-panel cable applications. Samtec’s Kevin Burt walks us through the demo, the results, and a brief discussion of the benefits. What's Going On On … [Read more...]
May the 4th Be With You!
"Hello there!" Any Star Wars nerd worth their weight in spice from Kessel knows who said that. Rightfully, Disney+ released a new full-length Obi-Wan Kenobi trailer. If you haven't watched it yet, you should! It would be a lie to say that I am not geeked about this trailer and the upcoming Disney+ series. While this may appear like a shameless blog, Samtec has a long history of appreciating Star Wars geekery. Aside from the fun, sci-fi culture is definitely associated with bleeding edge … [Read more...]
