Characterizing & Debugging EMI Issues for Wireless and IoT Products

By Kenneth Wyatt

An increasing number of manufacturers are adding or retrofitting wireless technology into new or existing products. These products typically include mobile, household, industrial, scientific, and medical (ISM) devices. This transition towards “everything wireless” is in full swing, and with it comes problems with electromagnetic interference (EMI) from the product itself interfering with sensitive on-board cellular, GPS/GNSS, and Wi-Fi/Bluetooth receivers. Read on to find out what to do about it.

Resonances in Coaxial Connectors and the Impact of the Return Path Vias

By Dror Haviv

Why does a low cost through-hole SMA have a lower bandwidth than a surface mount SMA? The answer will surprise you. A coaxial connector is an electrical connector designed to work at frequencies in the multi-GHz range. Coaxial connectors are widely used in high-speed analog and digital applications.

Characterizing the VRM

This SI/PI Technical Session on September 12 at 11:00am presented by Steve Sandler, will cover the test bench setup to perform the measurements needed to characterize the predominant VRM noise paths. These measurements provide a roadmap to optimizing the VRM from a system level perspective, ensuring power integrity, while minimizing VRM noise that degrades performance of other system circuits.

Measuring and Interpreting Impedance Data

Power integrity engineers have been learning to make VRM impedance measurements to compare to the design goal or “target impedance”. Once the measurement has been performed, it’s important to be able to interpret the data. Is the result good or bad? What do I need to do to improve it? How does the impedance measurement relate to step load response and control loop stability? This webinar addresses all of these topics, providing you with the ability to perform accurate measurements, analyze the results and relate the impedance to step load response and control loop stability. It's not too late to register, join us on August 22nd!
