When Do You Need Low-Dk PCB Laminates?
Designers looking to build more advanced systems operating at higher data rates and bandwidths tend to rely on materials with low dielectric constant values, i.e., low-Dk materials. It has gotten to the point where every high-speed PCB design guide implies that high-speed and RF designs will not function without a low-Dk material like Rogers or Arlon. The reality is that … [Read more...]
Essential Performance for Medical Products
Introduction Essential Performance has been a mysterious term ever since its introduction in International Standard IEC 60601-1-2 in 2001. Essential Performance is not unique to IEC 60601-1-2, but originates in the general standard, IEC 60601-1, and is used throughout all the collateral and part 2 standards of the IEC 60601 family of standards for medical electric equipment, … [Read more...]
Static Control Resilient Flooring Qualification Procedures Ensure Space and Defense ESD Compliance Pt. 1
Due to the rapid densification of ESD sensitive devices (ESDS), static control resilient flooring (ESD flooring) has found its way into FAA towers, operating room theatres, MRI/CT scan flooring areas, aircraft terminals, IT data centers, Navy ships, space & defense flight lines, call centers, medical device manufacturing, pharmaceutical delivery and the … [Read more...]
Using a TEM Cell for Radiated Emissions and Immunity Troubleshooting
Many companies would welcome a full EMC compliance test chamber if it weren’t for budget and real estate considerations. Yet, they would like the opportunity to develop a low-cost troubleshooting solution for assessing radiated emissions and radiated immunity prior to going off for formal compliance testing. While I’ve written many articles [References 1 to 8] on how to … [Read more...]
Advantages of Using a Pre-Certified Radio Frequency Module in an IoT Application
Learn the benefits of using a pre-certified radio frequency (RF) module in the design phase when building a new IoT application, and learn the implications in EMC and Radio certifications. The Internet of Things (IoT) is revolutionizing the quantity and manner in which we exchange and store information. Historically, people exchanged information through reading and … [Read more...]
Space Weather – Predicting EMC Effects of Solar Storms
When we think about weather, we know what it is. We feel it, worry about it, and talk about the heat, the moisture, the wind. Weather is dynamic, though mostly predictable because we can measure its conditions. We also know that the atmosphere involves large scale electrical activity. Cloud masses move above and below each other, generating enormous static-electricity … [Read more...]

Simultaneous Operations (SIMOPS) of Radio Systems Due to Antenna to Antenna Coupling on an Aircraft
Although specifically dealing with aircraft systems, the methods described in this article are applicable for other platforms where a number of antennas are in close proximity. The number of antennas in use and in close proximity on mission specific aircraft are as many as 22 on a small search and rescue aircraft. ANALYSIS METHODS The methods of coupling analysis include … [Read more...]
Use of Ferrite-Loaded Absorber to Reduce Wireless Self-Interference
Self-generated EMI from DC-DC converters, as well as digital and video processing, has long plagued designers of wireless and IoT devices, especially since physical sizes have trended smaller. The broadband harmonic content often extends up through 1.5 GHz, which includes most wireless protocols, cellular LTE and GPS/GNSS bands. One new mitigation technique I’ve been trying … [Read more...]
