Clash of the Titans - GaAs vs CMOS PAs

Will CMOS finally conquer GaAs in handsets?
April 13, 2013
Having traveled to Barcelona for Mobile World Congress (MWC) in late Feb, heading back out to Beijing for EDI CON 2013 in early March and then returning quickly to get the May IMS 2013 issue in ready, I am only now catching up with some of the items of note from these shows. The one item that sticks out in my travels is the Qualcomm announcement.  Although there has been some commentary about Qualcomm announcing the RF360 Family just prior to MWC, it is surprising that it has not gotten more attention as it could turn the industry upside down.

PCB Formulated For Reliability

May 3, 2013
Achieving high reliability for a high-frequency circuit or system starts with the printed circuit board (PCB). The PCB material must deliver consistent performance over time and changing conditions, such as temperature. As explained in the previous Blog (part one of this two-part series), it is possible to spot PCB materials that are “built to last” by assessing a number of their key performance parameters, such as coefficient of thermal expansion (CTE). In fact, PCB materials such as Rogers RO4835™ laminates can be engineered for high reliability through a careful combination of material components resulting in specific performance characteristics.

Picking A PCB For High Reliability

April 16, 2013
High reliability is a goal and desire for all designers and end-users of high-frequency printed-circuit boards (PCBs). Since all of the components mounted on the PCB depend on it, it is expected to deliver dependable and consistent performance over time. But depending on the operating conditions, it can sometimes be difficult to achieve. In an attempt to help, the next two Blogs will explore PCB material reliability: this blog, Part 1, will review some of the general obstacles for a PCB material to achieve good long-term reliability while the next blog, Part 2, will take a close look at how the characteristics of one particular PCB material add up to good long-term reliability.

Looking Back Over Using PCB Materials

50th ROG blog posting
April 1, 2013

This ROG Blog series on printed-circuit-board (PCB) materials from Rogers Corp. (www.rogerscorp.com) has reached the half-century mark, already covering a wide range of topics on circuit materials with this, the 50th ROG Blog. It has even detailed the effects of different PCB material thicknesses on circuit performance, and described the influence of conductor roughness on circuit performance. While it would be difficult to pick out the top 10 Blogs from the first 49 Blogs appearing since August 2010, at least 10 of these ROG Blogs deserve mention for how they have attempted to help readers with their different uses of PCB materials.

Practical test needs trump instrument silos

October 29, 2012

Justin PanzerWireless communications industry veteran Justin Panzer brings his insights to this edition of the Tek Talk blog. He has more than 19 years of industry experience, including 10 years in test and measurement working on everything from commercial handset testing to mil/gov RF. He is currently business development director for the Sources & Analyzers Product Line at Tektronix. He holds a Bachelor of Science from Drexel University and an MBA from Auburn University.

Ubiquity of wireless communications is adding an RF component to electronics designs that haven’t historically been wireless enabled. More complex chip, board and embedded systems designs that incorporate communications technologies into everything from PCs to automobiles are changing the impact of RF on the world's R&D engineers. Designers today need the tools to get the most out of unfamiliar technologies.

The Diagnostic Powers of Test

September 22, 2012

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.

Prototyping for Success

August 15, 2012

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

The prototype phase plays a critical role in the development of advanced RF/microwave components and assemblies.  For design and process engineers, this phase is all about learning how the part performs and gaining insight for building the final product. Like many things in life, work and business, good communication is paramount to success, and it is critical that the design and process engineering teams work cohesively to capitalize on the opportunities for learning that prototyping provides.

Drivers that Drive us Nuts

May 17, 2013
You know what amazes me? Design software. Agilent, AWR, Mentor Graphics, Zuken…all of them amaze me! The power, the flexibility and the add-on tools that I often read about are truly stunning. Of course, not being a designer or engineer I am relatively easy to impress. Yet I do remember the design tools of old, and they didn’t contain a fraction of the power and features today’s tools offer. I am also amazed by the people who so deftly use these tools to design PCBs. These designers lay out boards that would have seemed like science fiction just a decade or two ago.

Slowing down to Speed Up

April 16, 2013
Its official: I have become my parents. Everything I swore I would never do or say—I do all the time. It is beyond annoying! Lately, I catch myself repeating myself, or telling the same story, to the same person…Argh! I feel the exasperation of my 16-year-old-alter-ego rolling her eyes and sighing hopelessly. That being said, I’m about to do it again and you will be my latest victim. Sorry. I guess now I understand what my folks meant when they used to say “some things bear repeating.”

Dinosaurs and Fab Drawings

March 18, 2013
One frustration of making printed circuit boards these days is trying to make a board without a clear, respectable fabrication drawing. Apparently they have gone the way of the dinosaurs and are now extinct.  In the old days, a board house wouldn’t quote a job, much less build it, a without a fab drawing. Back then I schlepped around big plastic-wrapped sets of film with giant “D” sized drawings, while talking on a mobile phone the size of a brick. In those days, jobs didn’t start without a drawing, period!

Microwave & RF Engineers…Communication is Key!

May 1, 2013

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.

The Most Common High Power RF Design Error

January 6, 2011
Here in the Freescale Application Support Department, we get lots of calls from RF design engineers, who are in a desperate, crises mode. They have created a design using the best simulation tools possible and after having just built up their first prototype units, they are having some sort RF performance issues of varying degrees. Sometimes it is poor RF performance numbers not in line with the data sheet, sometime it is spurious oscillations, or shifting RF performance numbers with temperature or maybe even, in extreme cases, total device failures.

Into the wild blog yonder…

December 2, 2010
Ever since I began learning science and engineering at Duke, I was always struck with the sullen reminder that engineers are generally viewed by laymen as outcasts who know strange things and behave in even stranger ways. I’ve always hated this mischaracterization because I find, almost invariably, that scientifically minded people tend to be some of the most amazingly well rounded and talented people I know. I began writing this blog to dispel some of this bad press and to provide some “engineering-centric” content along the way. Ultimately, my goal was to provide a forum where real engineers could express their thoughts about both absurd and important scientific issues, free of the pressures of selling products and services.

Who’s better: Tom Brady or Steve Jobs?

September 16, 2010
During the World Cup, I wrote a blog entry about technology in football (i.e. soccer). Owing to the popularity of that light-hearted techno-babble and the excitement surrounding the start of the NFL regular season, I have decided to write another (silly) article about another (fruitless) pastime of mine: fantasy football. I have done a lot of thinking about fantasy football (for those of you unfamiliar, fantasy football is detailed here), and my conclusion is that it is a superior waste of time.

A Case Against Patents

August 25, 2010
People often ask me how many patents Marki Microwave owns. The answer: zero. “What? But you’re a technology company, how can this be? Aren’t you worried that someone is going to steal your idea?” Well, not really, and I will try to explain the logic behind this position. Some will read this and disagree, I have no doubt. I actually think patents do have important benefits given the right set of circumstances, but I think for small tech companies like Marki Microwave, patents do not provide as many benefits as is often assumed. I believe it is false to assume that a good idea should always be patented, here’s why…
