Hello, Welcome to the Altium Learning Hub

Controlled impedance routing at high frequencies is difficult enough, and it's important to make sure that you stay within your loss budget on long routes or in lossy media. When you have to route a long trace or a long differential pair to a connector or another component, what can you do if you're reaching the end of your loss budget? Most designers will tell you to just use an alternative low-loss/RF material that has a lower-loss tangent whe...

Dr. Eric Bogatin, Dean of Signal Integrity Academy is back for some awesome discussion about bad PCB design guidelines. How to spot them to avoid ruining your design? This is going to be fun and insightful! Make sure to check the show notes and additional resources below. Watch until the end, our favorite Dean has some perks for our listeners.

AC to DC power conversion starts with a deceptively simple device: the transformer. These components use magnetic induction to transfer power between two coils without requiring a direct mechanical connection by varying the current in one of the coils. There are many types of transformers that can be mounted to your case/chassis, or directly to your PCB. In this article, we’ll look at some of the PCB transformer options you’ll find available that...

What most people don’t seem to grasp is that every aspect of the PCB is critical. It all plays a significant part in the operation of the final product. The layer stack is no different. We need to keep in mind materials and the intricacies therein, including thickness, weave, dielectric constants, and more. A proper layer stack is needed for each and every design, so it's important to know how to navigate the layer stack manager and all of its...

Today’s PCBs contain many transmission lines. Combine this with increased clock frequencies and data rates and the result is a critical challenge to high-speed design. Neglecting these dynamics can undermine product development by compromising performance, power consumption, EMC/EMI compliance, and more - leading to delayed design cycles and opening gaps that can be exploited by your competition. Hone your high-speed design skills by joining us...

Assistants in the form of speakers, such as Google Home and Amazon’s Alexa, have managed to find their way into countless homes these days. They connect with our smart lights, speakers, thermostats, and almost anything that begins with “smart.” Tinkerers and engineers have discovered that they can also make their widgets “smart” and control them with their smart speakers as well. Tutorials for projects like smart robotic arms, homemade smart...
