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.

Two-dimensional jitter analysis
Seeing Jitter in an Eye Diagram
Using probability mass functions to represent both intersymbol interference (ISI) and jitter, a method of statistical simulation can be developed to consider their effects in tandem.
Interference-Free Millimeter-Wave Radios Promise Security
Using unlicensed millimeter-wave bands may be the next step toward higher-bandwidth and higher-security commercial communications.
Vector Reflectometer’s Compact Size Brings Connectivity Advantages
Copper Mountain’s Planar R54 vector reflectometer, demonstrated by MW&RF Technology Editor Jean-Jacques DeLisle at IMS 2014, measures 117 by 39 by 19 mm and weighs 8.8 oz.
Solid-State Cooking Oven Gives Users Greater Control
Jean-Jacques DeLisle, MWRF’s tech-editor, demonstrates the process of a solid-state cooking oven at IMS 2014.
UV Laser Delamination Raises the Rapid-Prototyping Bar
To accelerate 2D-surface prototyping, LPKF equipped its ProtoLaser U3 with an ultraviolet (UV) laser to selectively delaminate and cut substrates.
Gallery: Filter Assemblies Boost Performance
There are a variety of techniques and materials used to optimize the performance of complex filter structures. Many of these structures are also parts of larger assemblies used in applications from telecommunications to military.
Looking Back at the 2014 IMS Exhibition
Many significant new products across a wide range of technologies were introduced at the recent IMS 2014 exhibition in Tampa, Fla.
Unmanned Aerial Systems’ Capabilities Soar
As the uses for unmanned aerial systems continue to expand, the variety of payloads and technologies incorporated into these platforms is creating industry-changing advances in mobile communications.
Enhanced MEMS Oscillators Catch Up to Crystals 1
The race for ever-smaller and higher-frequency components for the RF/microwave industry is forcing innovations on every component in the signal stream. MEMS technology enhanced by CMOS processes could be the ticket to smaller, lower-cost, and higher-frequency oscillators.
Filter Assemblies Boost Performance
Many RF/microwave applications require far more than a single filter. Using precision assemblies to combine filters, filter functions, and other passive/active components can lead to a higher-performance solution than embedding filters in existing designs.
Power-Amplifier Systems Get Smarter
RF/microwave power-amplifier systems traditionally have been chosen based on their SWaP-C characteristics. But recently, factors like intelligent features are being added to the mix.
Detailed Thermal Models Benefit IC Package Designs
Accurately predicting the temperature profile of an integrated circuit could lead to higher reliability, prevent latch-up, and improve performance.
RF Power MOSFETs Get Put to the VSWR Test
To ruggedize an RF power MOSFET, testing on a variety of load conditions is necessary. Under rigorous VSWR testing, failure mechanisms can be discerned and designs can be improved.
Interview with a Living Legend: Dr. Stephen Maas, President, Nonlinear Technologies Inc.
Dr. Stephen Maas has an extensive background in R&D of low noise and nonlinear microwave circuits and systems. He also is a prolific author and educator, chief scientist at AWR, and founder of Nonlinear Technologies.
60-GHz PLL-Based Modulator Boosts Radar Applications
Significant research efforts have been made to realize a cost-effective CMOS IC radar for automotive, security, and presence-detection applications.
