Geek Speek Webinar – Resonances, Modes and Cutoff Frequencies

Presented by: Kelly Garrison An introduction to non-TEM problems in SI design, or how knowing a little bit about waveguide will help with high frequency design. Several case studies will show the ways that a designer can be caught unawares both in simulation and in hardware, and how resonances can occur in structures you didn’t think could resonate. We’ll also cover the reason why connectors and cables are forced to get smaller and smaller as frequency increases, and an argument for escaping from TEM and embracing waveguide. Kelly Garrison has been a Signal Integrity engineer for 2 years at Samtec, working on Precision RF connectors, Glasscore, and Waveguide. He brings another 10 years of experience from the RF Test and Measurement industry, where he specialized in passive microwave component design. If you so much as think about filters, baluns, or waveguide, he will send you a Zoom link so you can talk about it. Kelly graduated from Portland State University with degrees in Electrical Engineering, Physics, and strangely, a minor in Russian, and still lives in the Portland area. He spends his days off fixing things that his four sons have broken and dreaming about the day when they’ll help him fix things that he’s broken.

“Supply chain.” Who knew that business term would become part of everyday conversation. Supply chain issues are everywhere. Key shipping ports and shipping lanes are finally becoming unclogged. Retailers have too much clothing, but not enough household supplies. Consumers can’t f...
(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, coming next week, discusses GN...
If you’ve been paying attention to the Coming Soon section in our most recent web updates, you might have noticed we have been working on an upgraded Checkout system for the website for the last several months. We’re happy to announce that this application is now accepting orders...
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 ...
This month, we released a major new version of our Checkout to a beta state, made some upgrades to how we show lead times online, made 3D model downloads easier from the Search, and released a few more content updates. Here are the major website updates to Samtec.com for July 202...
