"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...]
Compact Components Enable Compact Drones
According to the Drones Industry Insights Report 2020, the worldwide drone industry is predicted to increase at a 13.8% CAGR to $42.8 billion by 2025. Advancements in sensor technology are fueling innovation in the drone industry. In addition, increased embedded Ethernet speeds (2.5 Gbps, 5 Gbps, and 10 Gbps) enable faster throughput for the multitude of sensors found in drones. However, for this technology to work, new innovations must be compact and light because extra weight on a drone … [Read more...]
Crosstalk Measurement and Characterization in High-Speed Interconnect
"High-speed applications" means different things to different people. In automotive infotainment, a high speed may be 5-10 Gbps. For sensing applications, high speed may be one sample a second. In the data center, hosted data rates are 112 Gbps PAM4 with 224 Gbps coming soon. However "high speed" is defined, signal integrity becomes more essential for system optimization. At high frequencies, crosstalk becomes a challenge. High-speed differential pairs routed in close proximity affect each … [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...]
Next-Gen Blue UAS Framework 2.0 AutoPilot Features Samtec High-Speed Interconnect
UAVs, or drones, have been around for decades. Original drones resembled early generation fighter jets controlled from the ground and used as targets for test pilots. As time passed, drones served as high-tech reconnaissance platforms and high-precision offensive weapons in military applications In recent years, drones have found many commercial uses as well. Popular e-commerce platforms and global retailers are using drones for order delivery. Hobbyists and tourists use … [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...]
