Jean-Jacques DeLisle
Technical Editor

Jean-Jacques graduated from the Rochester Institute of Technology, where he completed his Master of Science in Electrical Engineering. In his studies, Jean-Jacques focused on Control Systems Design, Mixed-Signal IC Design, and RF Design. His research focus was in smart-sensor platform design for RF connector applications for the telecommunications industry. During his research, Jean-Jacques developed a passion for the field of RF/microwaves and expanded his knowledge by doing R&D for the telecommunications industry. Journalism was always a passion of Jean-Jacques’ as well. He enjoyed writing for RIT’s university publication in addition to working on white papers, patents, and technical articles.

Jean-Jacques is excited to cover the latest trends in research, technology, and products. He is also determined to help engineers gain access to information services, which will aid in the design process while preventing many engineers from having to "reinvent the wheel"--a problem that is so common to the field.

Pinpoint the High-Frequency Resistance of Toroidal Windings
Using finite-element analysis and modeling mathematics, it’s possible to develop formulas and graphs that help to calculate the high-frequency resistance of single- and double-layer toroidal inductors.
These 11 Specifications Define PIN-Diode Switches 1
From switch type to compression point, PIN-diode-switch parameters must be precisely specified during system-level design to ensure functional or optimized end products.
Wireless communication
Scientists Compare Phase Noise With Vector OFDM
Because V-OFDM has been shown to generally outperform OFDM, researchers are interested in analyzing it and performing preliminary compensation for phase noise studies with V-OFDM systems.
Connectivity
Compare HetNet Cost and Capacity from 0.7 to 28 GHz
In an attempt to assess the cost-effectiveness of different heterogeneous network implementations, researchers studied the deployment and evaluations of several path/propagation loss models.
Wireless
Researchers Demonstrate SDR-Based Wireless Tomography
To enhance RF remote sensing technology, researchers used phase-reconstruction techniques and modern SDR devices to create tomographic maps of objects.
What’s The Difference Between Noise Terms and Noise Generators?
Noise negatively impacts the performance of almost every RF/microwave system; therefore, understanding how engineers describe it will help pinpoint the best noise-mitigating design considerations.
Software Reveals Cosite Challenges
Cosite challenges are increasing exponentially alongside the growth of radio systems used in most applications. Simulation software that predicts cosite issues and optimizes antenna placement has recently been enhanced with libraries of common radio systems.
To Balun or Not to Balun?
Because most IoT RF integrated circuits (RFICs) have differential transceiver (TRX) ports to the antenna, using a single-ended antenna architecture therefore requires a balun.
5 Antenna Topologies Squeeze into IoT Modules
Merging sensor, computing, and radio technologies into a single module is creating significant interference challenges for the radios inside complex IoT devices. Many antenna design techniques achieve the desired size reduction, but at the cost of performance tradeoffs.
Inside Track with Lorne Graves, Chief Technologist for Mercury Systems
Technology Editor Jean-Jacques DeLisle talks with Lorne Graves, chief technologist at Mercury Systems, about the OpenRFM initiative targeting defense systems.
4 Major M2M and IoT Challenges You Need to Know
The industry now faces the challenge of solving the complex issues of radio transmission, networking, low power, and high data rates in IoT applications.
Ambient RF Energy Supports Wireless Sensors
Investigators from the U.S., Canada, and Spain study far-field, low-power-density energy-harvesting technology to enable self-sustaining wireless platforms.
Organic Substrates Aid Ultra-Miniaturization of WLAN Receiver
Using chip-last embedded actives and passives in low-loss organic substrates, researchers from the Georgia Institute of Technology are able to implement an ultra-thin WLAN Rx module.
Printing Wireless IoT Sensors
Researchers from Toulouse, France, use inkjet printers to deposit carbon nanotubes on paper and other organic substrates, thus enabling IoT smart skins and zero-power electronics.
LTE Device Testing: from Theory to Measurement
As more mobile devices are being equipped with LTE technology, understanding both theory and practical measurement techniques is necessary for everyone from troubleshooting technicians to design engineers.
