Last June I spent a week and a half in Europe visiting Sweden, England and Italy. Bill Bazzy and I started the trip together; however, except for two days in Sweden and a day in Rome we went our separate ways. Sweden In Sweden I spent a good deal...
Tracing from Maxwell, through World War II to the communications boom and beyond, this report provides an insight into Europe’s historical role and the part it continues to play in the development of the global microwave industry. When Ted Saad and Bill Bazzy took their “Flight into the European...
The digitally-controlled attenuator (DCA) is a fundamental element of any system that combines microwave components and embedded digital control in its architecture. It consists of a bank of fixed attenuator pads, each of which can be switched in or out to adaptively select the optimum signal level for a...
Over the last few months I've had conversations with authors and reviewers which reveal that some elements of our editorial policy would be well put down in writing for all of us to consider. With a clearer picture for ourselves, we can better project encouragement to colleagues when we...
For those who want a change from technical meetings occupied with graduate student excercises and slides full of equations, there is the Allerton Antenna Applications Syposium. This is a brief report on the most recent, held September 20-22, 1978 at Robert Allerton park, about 25 miles west of Champaign-Urbana,...
With its Bridging Gaps theme, the 11th European Microwave Week couldn’t be held in a more suitable city than Amsterdam. Known as the ‘Venice of the North’, the canals that give it that name are spanned by 1281 bridges. They range from the famous Magere Brug (Skinny Bridge; see...
As European Microwave Week (EuMW) returns to its inaugural host city of Amsterdam, we would like to take the opportunity to outline the history of EuMW, the role of the European Microwave Association (EuMA) and the latest developments. The story starts with Peter Clarricoats who, on joining GEC in...

In wireless handset design, specifically power amplifiers (PA), there is constant pressure to improve time-to-market while maintaining high yields. To meet these demands, designers need to evaluate current design practices and identify areas for improvement. Presently, most PA designers spend a great deal of time bench-tuning to optimize circuits....
The use of passive repeaters for mobile communications is often discarded because of the inherent losses that these systems introduce. However, the radio signal coverage of indoor areas poses a particularly complex problem in buildings with heavily reinforced concrete walls and shielded or underground infrastructure, which introduce great attenuation....
