Why Is Apple Stockpiling RF Engineers?
Paul Chang, former principal engineer, project manager, and RF chip lead at Broadcom, recently migrated to Apple, further substantiating rumors that Apple plans on designing and building baseband processors in-house. Chang worked at Broadcom for over 11 years, helping develop a “series of cellular mobile communications CMOS semiconductor products,” including a number of 65 nm quadband single chip transceivers.
What Can Micro-Windmills Teach Us About The Future Of Medical Device Design?
At some point in the not-so-distant future, you’ll be able to recharge your smartphone by waving it about in the air for a few moments or (less conspicuously) by simply holding it out in a stiff breeze.What does this have to do with medical device design, you ask? Quite a lot, as it turns out.
Millimeter Waves For 5G: Intel Among Those Making Strides
Recent updates from organizations including Intel, indicate that the development of 5G mobile device technology is well underway, and that 5G networks will utilize millimeter waves.
Millimeter Wave Subassemblies Enable Next-Generation R&D Projects
Millimeter waves are being used to deliver critical course correction to subatomic particle beams travelling at 99.995 percent of the speed of light in the Relativistic Heavy Ion Collider (RHIC). By Jeff Elliott
Trends in automotive safety are pushing radar systems to higher levels of accuracy and reliable target identification for blind spot detection and collision prevention assistance. Consequentially, engineers need to better understand how mounting brackets, fascia, paint color, and bumper assemblies affect the far field radiation patterns of 24 GHz and 77 GHz automotive radar systems.
This white paper discusses the modeling of microwave cavities and demonstrates how a system for heating test samples was optimized using electromagnetic simulation.
The use of printed microstrip couplers in power amplifiers operating at microwave frequencies above 1GHz has been well established and numerous papers have been written about the design of such structures. It is surprising, however, that little has been written about the subject of printed baluns (BALanced to UNbalanced)— electrical devices that convert between a balanced signal and an unbalanced signal. Even more surprising is that the dominant approach to power combining at VHF and UHF is via coaxial cables, which comes with inherent assembly, cost, and thermal issues. By AWR with contributions from Dr. Dominic FitzPatrick of PoweRFul Microwave
The last time you installed a network application on your home computer, did you need a project manager and a multimillion-dollar budget? You might have set up an email client or Skype so you could chat with people on the other side of the world. In doing that, you integrated with the largest network in the world in only a few clicks. So why, to have a new tactical application, do you have to wait months, or even years, and secure a huge budget to pay several layers of contractors? By Stuart Marsden, tactical communications consultant and former British Army Major
Pulsed VNA Measurements: When And Why Do I Need To Re-Calibrate?
This is the final installment of a guest series written by Walt Strickler of Anritsu Company.
EM De-Embedding Magic – Part I: What’s the Problem, Anyway?
Way, way back in 1986, when I was developing the Method of Moments software that we are selling today , , I encountered (and overcame) many problems. One problem first became apparent when I was demonstrating prototype software at HP (now Agilent, soon to be Keysight Technologies) in Santa Rosa, one of my research sponsors. The results did not look so good. When we compared the results to measurement, the differences steadily increased as we went up in frequency. My funding from HP could be in jeopardy. Not good. By Dr. James C. Rautio, president, CEO, and founder, Sonnet Software, Inc.
RF Signal Capture And The Beauty Of The Digital Domain
From defense systems to wireless communications networks, bandwidth is an issue to be reckoned with. In the defense industry, electronic warfare (EW) systems in particular have always needed as much of this commodity as it can get, but it has now been joined by radar systems that have operating bandwidths in excess of 1 GHz, which presents significant challenges for their designers as well as those who must measure their performance. By Jim Taber, director of sales and marketing, X-COM Systems
