News From Washington Raytheon Awarded Contract for Eight US Navy Reconnaissance Pods Raytheon Co. has been awarded a contract with a not-to-exceed value of $19.2 M by the US Navy to produce low rate initial production of Shared Reconnaissance Pod (SHARP) systems. Under this contract, Raytheon Technical Services Co....

International Report Research Cluster Comes Together in Finland Micronova, the new microelectronics and nanotechnology centre for Finland, has been inaugurated in Espoo. A joint project of the Technical Research Centre of Finland (VTT) and the Helsinki University of Technology (HUT) the centre houses three research areas of VTT Information...

The Commercial Market Enterprise Business Information Technology Expenditures 2002-2006 In-Stat/MDR estimates that US enterprise businesses (firms with 1000 or more employees) spent more than $225 B on information technology (IT) in 2002, up three percent from 2001 estimates. By 2006, In-Stat/MDR estimates that enterprise firms will spend nearly $256...

Microwave Radio Links, from Theory to Design Carlos Salema Wiley Interscience 474 pages; $79.95 ISBN: 0-471-42026-3 This book introduces the reader to the principles and the design of microwave links. It can be used as a textbook for upper level engineering students and a reference for the practicing engineer....

Broadband synthesizers based on direct digital synthesis (DDS) technology have traditionally led the industry in frequency agility and switching performance, but have also led in high NRE and recurring costs. These high costs stem from the custom nature of DDS-based synthesizers and have resulted in digital synthesizers being primarily...

Enhanced performance is needed from antennas, radomes and other microwave components to support ever-increasing functionality for military communications and electronic warfare (EW) applications. There is a continuing demand for antennas with broader bandwidth, higher power handling and better controlled radiation patterns, while at the same time reducing size and...

A number of factors are driving the design of high speed digital packaging. At the assembly level, metal boxes are the dominant configuration due to mounting and interconnect constraints. The next assembly connectivity is accomplished through cables, requiring coaxial connectors. Since a variety of companies manufacture many of the...

In recent years, GSM systems have been deployed using many base transceiver stations (BTS). However, in some areas, such as basements of buildings, tunnels and valleys, there may be no signal, and in some regions fading may occur. These problems can be solved cheaply by implementing repeaters. Figure 1...

When designing dielectric rod antennas for maximum bandwidth, maximum gain, minimum beamwidth and/or low side lobes, design parameters reported in the literature are provided in terms of free-space wavelength. While this methodology lends itself well to other antenna types, it is not as useful when used to describe dielectric...

Precise device characterization is the starting point of any good circuit design. This task can be particularly challenging when the device is a high power transistor having low input and output impedances. For devices working only under pulse conditions, specific test benches exist 1 but are rather complicated and...
