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.

What’s the Difference Between IEEE 802.11af and 802.11ah?
Although IEEE 802.11af and 802.11ah are both sub-1-GHz standards, they are designed to fill different niches in upcoming IoT and wireless-backhaul applications.

Dynamic range is a limiting factor for many of the latest testing and measurement applications.
6 Technologies and Techniques to Know for Measuring Noise Figure
For noise-parameter and noise-figure measurements, tradeoffs can be made between cost, time, frequency, and quality, depending upon the test equipment available.
MMIC Quadruples Frequencies into Millimeter-Wave Bands
For 5G to be realized, circuit designs must aid current technologies in reaching the millimeter-wave bands cost-effectively without minimizing performance.
Linear-Beam-Based RF Amplifiers Suffer From Electron Emittance
With higher-frequency operation, the effects of electron-beam emittance are a more significant concern for RF/microwave devices.
Inside Track: Chris Kneizys, President/CEO of Micro-Coax (Part 2)
Probably the most common means of protecting these materials from oxidation is through the use of barrier coatings.
Inside Track: Chris Kneizys, President/CEO of Micro-Coax (Part 1)
The materials used for these different types of cable do not vary all that much. Obviously, the construction and longevity of the product depend upon type.

At IMS 2015, there will be a plethora of special events, honorary sessions, exhibits, and even a boot camp or two.
The Evolution of Microwave and MM-Wave CMOS ICs
Since the 1970s, researchers and engineers have been advancing the techniques and technology necessary to enable the next wave of low-cost and highly integrated RFICs.
IMS 2015 Welcomes Women in Microwaves, STEM, & Young Professionals
At IMS 2015, the Women in Microwaves (WIM), a subset of the Women in Engineering (WIE) group, is hoping to boost the number of female engineers in the microwave and RF industry.
Welcome to IMS 2015: Finding Your Way Around the Symposium
Microwave Week is rapidly approaching, again providing the opportunity to reaffirm outstanding relationships, explore the smorgasbord of microwave products/services, and dive into the latest and greatest technologies that the microwave industry has produced.
What’s the Difference between OpenVPX, OpenRFM, and MORA?
Employing open and modular platforms for RF/microwave systems could substantially decrease initial cost and maintenance while reducing the time and cost of upgrading legacy systems.
300-GHz Transceiver Boasts On-Chip LO and Mixers
Researchers from Korea and the United States designed a 300-GHz transceiver for wideband communications and imaging applications. It houses fundamental local oscillators and mixers on a 250-nm indium-phosphide double-heterojunction bipolar transistor process.
MEMS Switch Hits Millimeter-Wave Frequencies
Researchers from Canada explore a waveguide structure internally lined with MEMS cantilever actuators in order to realize a millimeter-wave switch that can operate from 60 to 75 GHz.
Cardboard and Inkjet Printed Silver Make One Good Power Harvester
Researchers from Finland and the U.S. designed an environmentally friendly 800-to-1500-MHz energy harvesting antenna using biodegradable materials. In doing so, they developed a fabrication process that achieved reasonable energy efficiency over a wide bandwidth.
