New power-semiconductor technologies like SiC and GaN enable increased efficiency and higher switching frequencies, which allows smaller component sizes. But these gains come at the expense of greater radiated electromagnetic emissions, just as EMC regulations are getting tougher. How can engineers effectively minimize radiated EMI?

The 2018 IEEE EMC+SIPI event returned to Long Beach, CA after last visiting in 2011. The event continues to include Signal Integrity & Power Integrity (SIPI) as part of the conference, reflecting the EMC Society’s influence and focus on this critical topic of engineering design.

Würth Elektronik eiSos, manufacturer of electronic and electromechanical components, announces WE-MCRI - a novel double choke: It is the first of its kind with molding technology. With its soft saturation characteristics, a WE-MCRI is above all suited for DC/DC converter applications.

Artech House today announced the publication of Intersystem EMC Analysis, Interference, and Solutions by recognized expert Uri Vered. This comprehensive new resource provides methods and tools for defining EMC requirements and techniques for performing predictions and calculations to achieve electromagnetic compatibility.

Automotive designers can significantly lower EMI and increase efficiency with the pin-compatible MAX20073 and MAX20074 buck converters from Maxim Integrated Products, Inc. The compact converters, which offer one of the lowest EMI performance for low-voltage point-of-load applications, which are ideal for automotive infotainment and ADAS applications.

Receiver sensitivity and noise coupling to antenna are two major concerns when developing mobile devices such as smart phones and tablets. There are various causes of degradation of receiver sensitivity. However, most of the time they are due to the noise generated by digital signal harmonics on printed circuit board (PCB) patterns, which couple to the antennas. This article presents a methodology to predict noise to antenna coupling and antenna desense.

The new EMI receiver TDEMI® ULTRA from GAUSS INSTRUMENTS provides industry-leading features, such as a 685 MHz real-time bandwidth, fast receiver scanning and multi GHz real-time scanning up to 40 GHz. It is a multi-purpose instrument for a wide range of applications and due to its compact design, a 12V supply, and a weight of less than 10 kg it is a fitting tool for field testing or on-board testing applications.

Manufacturers of electronic equipment for Hi-Rel applications often struggle to meet stringent EMC and safety standards.  Knowles Precision Devices (KPD) has a range of EMI components, under the SYFER brand, that particularly appeal to designers in the medical implantable and space sectors as well as industrial, automotive, aerospace and telecom applications.

At EMV 2018, Rohde & Schwarz will present its customized solutions for EMC measurements in all areas of product development, from the R&D phase to certification. A turnkey test system for certification testing in line with RED as well as complete systems for immunity measurements will also be on display.
