News From Washington US Air Force Awards Harris Corp. Space-based Radar Payload Design Harris Corp. announced that it is one of three companies awarded three-year contracts by the US Air Force to develop and demonstrate a prototype radar payload for Space-based Radar (SBR), a critical national defense program. The...

International Report Project MESA Takes Protective Measures An aggressive work plan to revolutionize communications for organizations within the public protection and disaster relief sector has been adopted by Project MESA. The plan was agreed during the sixth plenary meeting of Project MESA, which was held in Ottawa in April...

The Commercial Market Small Business IT Expenditures 2002-2006 In-Stat/MDR estimates that the small business market (firms with 5 to 99 employees), in aggregate, spent more than $154 B on information technology in 2002, up almost four percent from 2001 estimates. By 2006, In-Stat/MDR estimates that small businesses will spend...

Modern Microwave Transistors - Theory, Design and Performance Frank Schwierz and Juin J. Liou Wiley Interscience 486 pages; $89.95 ISBN: 0-471-41778-5 Microwave transistors are the backbone of modern microwave systems. In recent years they have undergone an impressive evolution, where continuous research efforts have made transistors faster and more...

The fast fourier transform (FFT) approach to the method of moments (MoM) is well known for providing high accuracy, high dynamic range and robust electromagnetic (EM) analysis of planar circuits. The FFT consistently calculates the coupling between subsections to full numerical precision; no error is introduced by complex multi-dimensional...

In the telecoms and other RF component markets, today's climate means that there can no longer be a trade-off between cost and performance - the designer needs to achieve both. Temex has recognized this fact and addressed it through the evolution of two new generations of materials on which...

This is the best time to be a consumer of electronic products. Wireless mobile devices, especially cellular handsets, have more features, are smaller and have better battery life than ever before. The cellular handset manufacturing industry is continuously challenged to deliver high performance, cost-effective, small form function products to...

The basic principle of operation of a MESFET multiplier is that the device is biased for a particular conduction angle, based on the harmonic frequency to be generated. A generalized circuit schematic of a MESFET frequency multiplier is shown in Figure 1 . It can be seen that the...

One of the greatest challenges in characterizing new coaxial interfaces is to determine an accurate test configuration. When precision airlines are not available it is very difficult to obtain a true measurement of the device under test. It becomes necessary to design and implement calibration standards to eliminate the...
