Members of the public could form the backbone of powerful new mobile internet networks by carrying wearable sensors. According to researchers from Queen’s University Belfast, the novel sensors could create new ultra high bandwidth mobile internet infrastructures and reduce the density of mobile phone base stations. The engineers from Queen’s renowned Institute of Electronics, Communications and Information Technology (ECIT), are working on a new project based on the rapidly developing science of body centric communications. Social benefits from the work could include vast improvements in mobile gaming and remote healthcare, along with new precision monitoring of athletes and real-time tactical...

If you think working in an office or a lab is tough, imagine repairing equipment on top of an antenna tower at over 1,700 feet. This video is making its way around facebook and is certainly not for people who are afraid of heights. As impressive as the hardware is, operating outdoors under extreme environmental conditions, I must express equal respect for the linemen who service these towers. Test and measurement vendors have been producing a number of handheld instruments designed to make their jobs easier and safer. I just can't imagine operating a VNA or spectrum analyzer from...

It happens in my house late and night or early in the morning, when I forget to turn off my Blackberry and the stream of incoming e-mail spams lead to pick-up with the audio portion of my clock radio, setting off an annoying buzz. It is highly likely that most of us have been in meetings, on conference calls or even watching television and have been victims of “the buzz” - that awful annoying feedback emitted from mobile devices when they are in close proximity to audio devices. That annoying buzz occurs when an electrical audio device amplifies a cell...

A is for agnostic nonlinear model support, the leading news from AWR in support of the Cardiff models, the latest S-functions from NMDG and X-parameters from Agilent B is for broadband time delays product line from Hittite , a DC to 24 GHz analog time delay that supports data transmission to 32 Gbps or clock signal delay up to 24 GHz. C is for cross correlation Phase Noise analyzers from Holzworth for either fixed or tunable DUT test frequencies. D is for distortion, an increasing concern highlighted by the importance of IM levels and a driving factor behind Creowave’s...

European Microwave Week was held in the CNIT convention center in the newer business center that lies to the west of the city’s center, a straight shot down Rue Charles de Galle, about three and a half miles from the Arc de Triomphe. The Center of New Industries and Technologies, or CNIT, is one of the first buildings to ever be constructed in La Défense, Paris. It is a palace for the French Congress that houses the main offices and also functions as a convenience store for the congressmen and their visitors. The initial construction of CNIT was completed...

Last evening I attended TriQuint’s customer presentation on their new TQP15 process, which was conveniently held at the hotel where I am staying. Enjoying the relaxed atmosphere, wine and canapés were two dozen or so representatives of MMIC design houses such as Plextek and Roke Manor, journalist, investors and other interested parties. Following the meet and greet with various TriQuint foundry management and marketing folks, the event centered around a presentation by Corey Nevers and Ed Knapp on the technical aspects and targeted applications of the new process. This presentation was followed by an informative Q&A session with attendees. TQP15...

Delegates were busy registering and attending the Monday sessions today as work crews unpacked displays and began building the stands for the 2010 exhibition. By mid-morning set-ups were progressing without much drama, in anticipation of the Tuesday opening. Since there are an impressive number of European Microwave companies engaged in nonlinear device characterization and the development of related test systems, it is appropriate that the European Microwave Week exhibition will feature a sizable representation of companies offering load-pull and related test solutions. Several of these companies were mentioned in last March’s cover story on non-linear Characterization and device modeling including...

It is hard to complain about location when the European Microwave Week makes its way to Paris once every half dozen years or so. It is a beautiful city. To quote an e-mail received from a M/A-Com attendee – “ PS - I love Paris!!!!”. I might take fault with weather.com, which predicted sunny days in the mid-sixties. Instead, the air is about 10 degrees cooler and the skies look threatening. Bringing my suede jacket was probably a mistake. Regardless, fall is a great time to be in the land of Coulomb and Ampére. I took the Saturday night...

To quote an e-mail received from a M/A-Com attendee – “ PS - I love Paris!!!!”. I might take fault with weather.com, which predicted sunny days in the mid-sixties. Instead, the air is about 10 degrees cooler and the skies look threatening. Bringing my suede jacket was probably a mistake. Regardless, fall is a great time to be in the land of Coulomb and Ampére.

Leading RF front-end chip manufacturers RFMD, Skyworks and TriQuint each released their quarterly earnings last week and the results for each were very encouraging with revenue for the quarter up 29, 44 and 23%, respectively over the same quarter of the previous year . For its fiscal 2011 first quarter, ended July 3, 2010, RF Micro Devices Inc. posted better-than-expected quarterly results, helped by growing demand for mobile broadband devices, and said it expects its September-quarter results to be in line with its first quarter. The company earned $28.1 million, or 10 cents a share, compared with $4.8 million, or...
