FCC Chairman Lays Out Innovation Based 5G Plan

Recommends Spectrum Allocation through mmWave Bands

FCC Chairman Tom Wheeler laid out his proposal for 5G spectrum allocation that he hopes will be approved by Congress on July 14. It is a comprehensive plan to designate spectrum in the low frequency bands, develop more mid-band frequencies in the crowed areas currently used and a gives specific focus to high frequency bands in the mmWave range. He stated that we will be the first in the world to approve these types of measures if Congress gives their approval next month.

Space Fence Goes GaN

Lockheed Martin recently released new information about their Space Fence which caught my attention since they are using GaN amplifiers in the system. Space Fence is a long range radar system to track and monitor objects and debris in orbit around the Earth. They announced that objects in space will soon be monitored by a radar array for the U.S. Air Force’s Space Fence as part of Lockheed Martin’s new test site.

How particle accelerator maths helped me fix my Wi-Fi

Electromagnetic radiation – it might sound like something that you’d be better off avoiding, but electromagnetic waves of various kinds underpin our senses and how we interact with the world – from the light emissions through which your eyes perceive these words, to the microwaves that carry the Wi-Fi signal to your laptop or phone on which you’re reading it.

EDI CON 2016 Opportunities Abound

This year marks the first that we are running two EDI CON conferences: EDI CON China on April 19-21 in Beijing and the new EDI CON USA on September 20-22 in Boston, MA. Both conferences include an exhibition, keynotes, technical conference sessions, workshops, networking, and training opportunities.

Brent's Musings

Your IoT, or Mine?

When it comes to the Internet of Things (IoT), Brent Dietz has found there's only one thing we all agree on: we don’t agree on what it is. Brent offers his ideas about what the IoT is and what it isn't.

For the Love of Trade Shows

Trade shows force us to redefine our sense of everything. Food has a different meaning; money has a different meaning; and if you’ve opted for front-lit foam board displays, your competitor has likely opted for GaN-powered neon and pyrotechnics.

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”.

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?

Flexible Circuits Are Just Around the Bend

Not all circuit materials are created equal, and some have more mechanical flexibility than others and can survive a certain amount of bending and flexing without damage. Understanding what makes a circuit material capable of bending and flexing, and what happens to it when it is bent or flexed, helps when specifying circuit materials for such uses.

Taming Temperatures in Multilayer Circuits

Multilayer circuits provide the means for achieving high circuit densities in small volumes. The penalty for the compact circuit sizes can be the challenge of dissipating heat from active devices, such as power transistors. There is a way to manage the heat without adding size, by distributing the heat throughout the multilayer circuit board, using a low-cost circuit material designed for that purpose, 92ML™ thermally conductive epoxy prepreg material.

Countdown to IMS 2015

If you are a delegate or workshop attendee, IMS 2015 is just 4 short days away! For exhibitors, like us at Zentech Manufacturing, we have 6 days until the doors open to the exhibit hall. Either way, don't blink, because we are just days away from the world’s largest international gathering of RF and Microwave professionals in the world!

“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.

Extending the Life of Test Systems that Support Long-term Programs

Jim Curran, Keysight Technologies, Inc. (formerly Agilent Technologies electronic measurement business)

At the beginning of every new product program, tremendous amounts of time, attention and money go into defining and integrating the required test system. The system is used to test the new products, ensuring that they function at the required levels and remain highly productive. The system is also expected to last for the life of the program.

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.
