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...]

Adaptors, Adaptors, Precision RF Adaptors
Chances are extremely high these days that you own at least one electronic device, which means you likely have an adaptor or two - or twenty. If you’re like me, then you probably have a box of adaptors “just in case.” We’ve recently added Precision RF adaptors to the Samtec website, highlighting the series options that will be available soon. Whether you’re connecting two alike or unalike interfaces, here you’ll find in-series and between-series adaptors for your application. No need for a … [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...]
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...]
RF Connector Tree: From MCX to 110 GHz
Samtec's RF Connector Tree is a display of Samtec’s RF products and their evolution into high frequency for microwave and millimeter wave applications. It is divided into six categories, or levels. This display was recently presented at DesignCon, IMS, and Embedded World tradeshows and conferences. In this video, Steve McGeary, Director of RF Business Development and Product Management at Samtec, walks us through the six levels, with an emphasis on precision RF and millimeter wave … [Read more...]
Introducing AcceleRate® Extreme Density and Performance Systems
The gang’s all here! We’ve recently pulled together Samtec’s family of AcceleRate® products into one webpage so you can easily browse and compare to find the best high-performance solution for your next gen application. The board-to-board and cable assemblies feature extreme density with up to 1,000 total I/Os on a 0.635 mm pitch and extreme 112 Gbps PAM4 performance. So, let’s get this party started with (re)introductions all around… Board-to-Board Interconnects First up is … [Read more...]
IMS 2022: New Technology, Millimeter Wave Connectors, and RF Launches
IMS 2022 is a week dedicated to all things microwave and RF. It’s the premier event where thousands of RF and microwave professionals will gather this June for networking, education, and to visit the exhibition. Samtec is looking forward to presenting our newest microwave / millimeter wave connector products, as well as showcasing some new technologies and applications in five live demonstrations and static displays. Microwave, Millimeter Wave Products Samtec designs and manufactures … [Read more...]
New 1.35 mm Precision RF Products to 90 GHz
Samtec has released its 1.35 mm family of products suitable for millimeter wave applications to 90 GHz. The 1.35 mm family includes compression mount board connectors (135 Series), cable connectors (PRF13 Series) and .047" low-loss flexible cable assemblies (RF047-A Series). 1.35 mm products are ideal for IEEE, E-band applications due to their high operating frequency and electrical precision. Samtec’s 1.35 mm board connectors are the industry’s only vertical compression mount product using … [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...]
