High Performance Sub 1GHz RF Project This week, I’m building a high-performance sub-1GHz transceiver that I want to use as a standalone Internet of Things node using the ARM Cortex M3 microcontroller. As with my other projects, this project is open source and published on GitHub for you to use as the basis of your own design, or to use as-is. The RF schematic and layout are production proven, as are the microcontroller schematic and all footprints on the board. However, do keep in Read Article Pad Stack Design And Fine Pitch Components, Part 2 What happens when you try to route two traces between pins on 1mm and below pitch BGAs? In Part 1 of this article, I reviewed the various aspects of unplated holes in the pad stack and what is needed to calculate the complete dimensioning of the finished hole size of the plated through-hole. Within this article, an analysis was done to determine how much room there was for traces between BGAs with a pin spacing of 1 mm on high layer count PCBs Read Article Frequency Modulation Simulation in Altium Designer When working with analog signals, you need to ensure your device is operating linearly in order to prevent problems like harmonic distortion during operation. Nonlinear interactions in analog devices lead to distortion that corrupts a clean analog signal. It may not be obvious when an analog circuit clips just from looking at your schematic or datasheets. Instead of tracing through your signal chain manually, you can use simulation tools to get Read Article PCB Trace Width vs. Current Table for High Power Designs Copper is a strong conductor with a high melting point, but you should still do your best to keep temperatures low. This is where you’ll need to properly size power rail widths to keep the temperature within a certain limit. However, this is where you need to consider the current flowing in a given trace. When working with a power rail, high-voltage components, and other portions of your board that are sensitive to heat, you can determine the Read Article WifiWall Technology Protects Against Cyberattacks Do you travel a lot? If so, do you use your smartphone, tablet, or notepad computer in airports or hotels? Even if you aren't a road warrior, do you use any of the aforementioned devices in public places like coffee bars? WiFiWall 5.0 Traveler (Image source: WiFiWall.com) In my case, I would answer with a resounding "Yes" to all the above. Of course, just about everyone these days knows that public Wi-Fi is subject to nefarious folks mounting all Read Article A Comparison of NVIDIA’s Embedded AI Computing Platform Options Each new embedded AI computing platform blurs the lines between man and machine... When I first got started with machine learning applications, specifically text classification and sentiment analysis, I was working with an eCommerce client building everything onto a web server. Given the huge amount of data we continue working with on a daily basis, it only made sense to build our platform on a dedicated server. For some AI applications Read Article Python and CodeBots Dragging Students into STEAM CodeBot. Image source: Firia Labs I have a friend. It's true. I'm not joking. Settle down. Look -- I'm not going to continue until you cease squirming in your seat and stop giggling. That's better. Now, if you're quite finished, we'll continue. We'll call my friend David (because that's his name). David is one of the cleverest guys I know. He has a size-16 brain -- the type with the go-faster stripes painted down the side. He has expertise with Read Article High Speed Design Features Growing Forward with Altium and Simberian Partnership Happy New Year from Altium! In our first article of the year we talk to Roger Paje, VP of Sales and Marketing at Simberian about our recently formed formal partnership and how their highly accurate field solver technology is helping usher in new high-speed design capabilities in Altium Designer such as layer stack, impedance and surface roughness modeling. These enhancements began in Altium Designer 19, were amplified in Altium Designer 20, and Read Article Altium 365: The New Frontier of Collaborative Cloud-Enabled Electronics Realization In this interview, we talk with Leigh Gawne, Chief Software Architect at Altium, to learn about Altium 365 and the impact he foresees that Cloud-enabled electronics realization will have on Design Engineers--as well as the entire industry. (To see Leigh Gawne and team collaboratively design a board LIVE in Altium 365 at this year’s AltiumLive conference, watch this video). Judy Warner: Leigh, please tell our readers about your background and your Read Article 1:3:28 Experience The New World-Class Interactive Router in Altium Designer 20 Altium Designer 20 ushers in a whole new era of possibilities and amongst them is a truly game-changing Interactive Routing Watch Video 30:28 Altium Designer 20 Meet The Next Generation Of Easy, Modern, And Powerful It’s time to meet the next generation of Easy, Modern, and Powerful PCB design.
