Propagation Pathways

 This is a blog about how to reproduce the propagation path of radars, radios, avionics, and altimeters. What we do at Eastern OptX—through technology and magic—is to reproduce the true path between the transmitted signal and the received signal. We replicate the path of the signal by providing “space” in between the transmitter and receiver. We generate that space.

SI and PI make impact at IEEE EMC

 Electromagnetic compatibility (EMC) is a field that studies the unintentional generation, propagation and reception of electromagnetic energy with reference to the unwanted effects (Electromagnetic interference, or EMI). Since this interference can fall within microwave frequencies it is not uncommon for engineers to have to address this issue when designing a complex, signal rich systems, from cell phone to automobile. The goal of EMC is the correct operation, in the same electromagnetic environment, between components (ICs) and electronic equipment that may radiate and create interference effects.

The Road to Rome

 International marketing for RF and microwave takes more than tact, cultural sensitivity and linguistic aptitude. It also takes a back-up plan. If you think that’s not the case, consider air travel in the US last week. We saw how a perfectly ordinary day can go crazy when one determined guy inside the FAA’s Chicago Center cancelled travel plans for millions. Travel normalcy is making a comeback, but the incident demonstrates why ‘business-as-usual’ isn’t always usual these days.

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”.

IMS 2014: Building Relationships

IMS 2014 hits Tampa Bay on June 1-6, 2014, and I bet you will be there. One of the largest industry events, the show is a must visit. This year it will be my 23rd IMS – wow! If you’d ask: what has changed over the last 20 years? I believe the show today is more personal. With social media becoming commonplace in our industry, we’re more connected and we can build stronger relationships without borders.

The Wonders of Waveguide

Why Use a Waveguide Variable Attenuator?

Waveguide-based high-frequency systems often require some control of amplitude or signal level. Waveguide attenuators can deliver that means of control, with fixed attenuators providing a single value attenuation setting and variable attenuators providing a range of attenuation control across a desired frequency range.

Find a Coax Fit for Waveguide

 Waveguide can provide outstanding electrical performance in terms of low insertion loss and low VSWR at microwave and millimeter-wave frequencies, but it may often be necessary to transition between waveguide and coaxial components. Doing so requires the right Waveguide-to-coaxial adapter and knowledge of how to integrate it into a design without introducing un-wanted chaos. The right adapter can provide convenience as well as performance.

The Diagnostic Powers of Test

HendrenBrian Hendren, Senior RF and Microwave Applications Engineer, Tektronix Component Solutions takes over the Tek Talk blog and discusses prototyping for success:

In this day and age manufacturers are trying to drive costs out of every aspect of the production flow, and RF and microwave is no exception.  That means that every process step gets closely scrutinized. Specifically,“test” is one of the operations constantly under evaluation to understand the bare minimum needed to verify performance.  That approach is understandable because test is likely one of the most time consuming steps in the production flow, particularly when you include system set up time.

“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.
