Another possible title for this blog was "I Designed A 50 Ω Transmission Path; Why is My Return Loss or VSWR Higher Than Expected?" Another was "Maintaining 50 Ohms In A Channel Is Trickier Than It Looks." Hopefully, you understand the main point we're trying to make. This blog is a summary of a seminar by Samtec's Michael Griesi, presented at IMS 2023. For those of you who weren't able to attend, a video of the full presentation is above. In the meantime, here's an overview of what Michael … [Read more...]
Military & Aerospace Soars Higher with Powell & Samtec
Samtec recently worked with our friends at Powell Electronics on a little marketing piece. The goal is to showcase our partnership related to Defense and Aerospace specific products Samtec supplies. Working with another family-owned, US-based company allows us to understand some of the nuances associated with the defense and aerospace industries. Any way that we can continue to grow our presence in the marketplace helps not only Samtec but the industry as a whole. A US-based manufacturing, … [Read more...]
Getting Help with Power Integrity
If you get your power design right, it protects the signal integrity margin and improves power and thermal efficiency. Some connectors combine power blades in addition to digital signal pins, which adds complexity. For these types of connectors, it is important to understand how the blade assignments impact power delivery as well as how the pin and blade assignment could affect signal-to-power and power-to-signal crosstalk. To assist designers with the Samtec AcceleRate® mP UDX connectors … [Read more...]
Living On The Edge Rate
Edge Rate® is one of Samtec's most popular high-speed, high-bandwidth interconnect systems. Edge Rate is both the name of the pin and in this case, it’s also a product family. Edge Rate Contact Design Let’s begin with the contact system because that’s the star of the show. With some connectors, the mating edge of the contact is the cut edge of the pin. If you look at the edge under a microscope you may see micro burrs and edges. This reduces the life of the connector because … [Read more...]
Why Use Flyover Cable Systems?
Samtec’s Flyover® cable systems are designed to get signals off the PCB in order to improve signal integrity, increase design flexibility, and optimize thermal performance. These products route high-speed signals through low-loss, low-skew twinax cable. They operate across distances that can be up to several feet long while removing the need for clock data recovery circuits (CDRs) or retimers. In a recently published white paper, Samtec Senior Field Applications Engineer, Anthony Fellbaum, … [Read more...]
New Waveguide Technology for Next-Generation Systems
As end-applications venture into the sub-Terahertz spectrum, Samtec has recognized the need for a new generation of products, one that incorporates an innovative approach by integrating a cable design that can support frequencies up to 90 GHz (E-band) with loss performance improved over today's coaxial cables. Enter our next-generation micro waveguide technology, offering the near-loss performance of a rigid waveguide while still providing the flexibility and size typically associated with a … [Read more...]
The Diverse Connector Market
The connector marketplace is one of the most diverse and interesting in the entire electronics industry. The roles that connectors are required to play range from the smallest data connections to the largest power supplies. They are frequently employed in some of the toughest conditions on Earth and despite this are expected to provide remarkable levels of reliability. As a result, the industry has responded with a quite bewildering array of choices. Many connectors are designed as … [Read more...]
A New Angle On Power/Signal High-Density Arrays
Angles surround us every day – physical angles like the corner over there, and angles of perspective. Samtec’s new AcceleRate® mP high-density power/signal interconnect system was born out of a different perspective on power integrity and a 90 degree rotation. Best in class density for a power/signal interconnect system, AcceleRate® mP achieves up to 240 I/Os in .438 sq. inches. It also packs a punch with up to 22 Amps per power blade and 56 Gbps signal performance. Rotated Power … [Read more...]
Wideband 24-30 GHz Phased Array Antenna Module Demonstrates Excellent 5G Comms Link
Wideband 24-30 GHz 5G mmWave capabilities are showcased in this demo by establishing an over-the-air (OTA) communication link between two Phased Array Antenna Modules, or PAAMs. Samtec's Jim Alexander walks us through one of several live product demonstrations from IMS 2023. This one is presented with our friends at Otava, Rohde and Schwarz, Taoglas, and Avnet. The modulated 5G FR2 signal is generated using a Rohde & Schwarz SMW200A vector signal generator which is sent to the … [Read more...]
Samtec’s New and Improved YouTube Channel
Hey Google! - "Clink" How do I download a Samtec 3D model? Most times when you are searching a topic, question, or how to do "blank", a YouTube video pops up with a solution. As the second largest search engine and video streaming platform, YouTube has revolutionized the way we consume, create, and share content. Every second of every day videos are being uploaded and posted to YouTube by individuals, media outlets, and major corporations. Samtec recently revamped its YouTube Channel with … [Read more...]
