Bandwidth to the Max - NIWeek 2016

NIWeek 2016 lived up to its usual high level of impactful new products and demos. The keynotes are always Apple-like with dramatic product introductions and interesting applications that have been enabled by their modular hardware and software. Of course, Dr. T kicked off the first keynote and discussed the first 40 years of NI as they celebrated their birthday this year. He discussed the evolution of modular instrumentation and NI’s vision of virtual instrumentation as today’s test and measurement equipment has become software driven. The processing power of the FPGA, driven by Moore’s Law, has increased tremendously over the years and the PXI platform has provided an open, modular platform. This has all been amplified by the NI user community and partners to grow the applications and uses of the NI platform worldwide.

An Industry Shift – Commercial AESAs

Active Electronically Steered Array (AESA) technology has been used in military systems, mostly radars, for many years. AESA systems have traditionally been too expensive for most commercial applications, but new phased array technologies are quickly enabling low cost commercial applications such as vehicle sensors, satellite communications and 5G cellular systems. These systems use beamforming techniques to more precisely deliver RF energy in concentrated beams giving more bits per Hz in the targeted area while reducing interference.

RF/microwave design software update for IMS2016

Performance of high-frequency electronics is continually advancing to meet increasing global demands for information. And while the cell phone has been around for over 40 years and the smart phone for over a decade, wireless communication systems are still evolving to address new applications and to handle more data throughput in the age of big data. Emerging technologies for future communication networks are hot topics among the talks and special sessions being discussed at this year’s International Microwave Symposium in San Francisco.

Make The New Year One To Remember

It is that time of year, at the start of a new year, to take stock of our time: our past, present, and future. Without becoming too philosophical, the break that many individuals and their companies take during the year-end holidays and into the New Year gives most people pause to think about their lives, whether they are goal-oriented or simply trying to figure out where they are in life and in their professions.

Two Decades at IMS and counting…

 When I first attended IMS in 1995 in Orlando, my wife was pregnant with our first child and complained about the heat all week.  I was 29 years old and slaved at a small ad firm with a couple of microwave accounts, but thought I was so cool with my permanent “car phone” after ditching my pager, and was one of the first AE’s to have their own web site, having spent nights learning HTML from Laura Lemay’s book, “Teach yourself Web Publishing in a Week”.

Filtering Through Material Choices

High-frequency filters are increasingly essential components within wireless products, especially as those wireless products continue to compete for limited frequency spectrum. Various types of RF/microwave filters help wireless radio transmitters and receivers operate with their proper signals while shielding them interference caused by out-of-band signals. For the best results, filter designers should start with a printed-circuit-board (PCB) material having optimum characteristics for RF/microwave filters. The choice of circuit material can not only impact a filter’s performance, but even the size of a printed circuit filter.

What Happens When Circuit Material Heats Up?

Heat can be damaging. Printed circuit board (PCB) materials are formulated to withstand a certain amount of heat, but when the temperatures rise beyond certain limits, circuit performance can suffer, especially at higher frequencies. Heat-tolerant PCB materials and carefully considered circuit designs can tolerate a certain amount of heat, if a circuit designer is aware of the various parameters that best describe a circuit material’s behavior when temperatures rise.

Differences Between Thermoplastic And Thermoset Materials

Two types of composite materials—thermoplastic and thermoset materials—are commonly used for the dielectric layers in PCBs or as adhesives in manufacturing circuit laminates and they each have their own traits and characteristics. But how do they differ? What are the strengths and weaknesses of each type of material and why choose one over the other for an application?

“Making the Impossible Possible” at IMS2015

 For the better part of the last year, I have been watching, with great interest, a company and PCB technology that may be a real game-changer. In fact, I became such an enthusiastic fan of eSurface that they invited me to join their advisory board last summer. eSurface Technologieshas developed a chemistry that enables PCB manufacturers to deposit metal directly to an unclad substrate, as opposed to subtractive print and etch processing.

Fully. Integrated. Supply Chain. Solutions.

 Since I am a writer, as well as an electronics professional, I have the quirky habit of really thinking about words. Which is why I started thinking about the commonly (if not overused) term Supply Chain Management recently. Having pushed off from the dock of my former narrow focus on Printed Circuit Board (PCB) fabrication--particularly those of the RF and Microwave variety--I now find myself in the deeper and more complex waters of Contract Manufacturing.

Microwave & RF Engineers…Communication is Key!

I recently agreed to co-chair the IEEE MTT-S Women in Engineering (WIE) / Women in Microwaves (WIM) organization. I have long been an advocate for advancing the cause of women in the world of RF and microwave engineering, actually back to my college days at Carnegie Mellon University (CMU) when I was one of only eight women in my EE graduating class of 110. Things have not improved much since then with women representing only 10 percent of the engineers in the U.S. today. Asia and Europe fair far better with approximately 40 percent and 20 percent respectively.

Reducing the Test Time Required to Calibrate a Multi-channel Antenna

By Dave Brannon and Alex Dickson, Keysight Technologies, Inc. (formerly Agilent Technologies electronic measurement business)

 For active antenna arrays, a significant amount of production test time is spent on calibration.  Large arrays can consist of hundreds or thousands of elements and it is necessary to characterize the phase and gain alignment between these elements to ensure precise beam-forming.  In addition, the test time to align these elements can increase dramatically as the number of elements increases.  Hence, the ability to accelerate test by using multiple coherent measurement channels is a significant benefit.
