News From Washington Harris Corp. Selected for Phase 1 of US Army's WIN-T Program Harris Corp. announced that it anticipates the award of a major subcontract from Lockheed Martin Mission Systems, Gaithersburg, MD, for the design and test of the wireless transmission system architecture as part of the three-year...

International Report lSEVIRI to Help Nowcasting Meteorology Successfully launched aboard the European Space Agency/European Meteorological Satellite's (EUMETSAT) Meteosat Second Generation (MSG)-1 satellite on 28 August 2002, the Astrium-sourced Spinning Enhanced Visible and Infra-Red Imager (SEVIRI) payload is set to radically upgrade the accuracy of nowcasting short-term weather forecasting for...

The Commercial Market Bluetooth is Steadily Gaining Market In the midst of the technology downturn, Bluetooth is steadily gaining market traction - evidenced by steady market growth in 2002 - and proving the skeptics wrong. Allied Business Intelligence (ABI) projects Bluetooth chipset shipments to increase to 33.8 M in...

Theory and Design of Microwave Filters Ian C. Hunter The Institution of Electrical Engineers 353 pages; $89 ISBN: 0-85296-777-2 Microwave filters are important components used in many RF and microwave systems, such as cellular radios, satellite communications and radar. The classic treatise on microwave filters and couplers by Matthaei,...

The humble signal generator has come out of its modest, functional shell and taken on a streamlined, compact, state-of-the-art persona with the development of the 3410 series. This family of digital RF signal generators has evolved in response to the worldwide growth of second- and third-generation wireless communications systems...

A new family of single- and dual-branch converter integrated circuits has been introduced for use in mobile infrastructure base stations. The new CV series converters are all priced below $10 in volume and are available in a 6 x 6 mm QFN package, as shown above. Their small size...

Double-balanced mixers are used extensively in transmitters and receivers. For frequencies below 5 GHz, the designs are normally realized using ferrite-based transformers, because they are very compact and their technology is mature. As the operating frequency increases, distributed element baluns become smaller in size and more attractive. Semiconductor-based mixers...

I find it hard to believe that it has been 12 years since Howard Ellowitz wrote a similar message announcing his retirement and introducing me as the new Publisher/Editor of Microwave Journal . Now it is my turn to slow down a little and find some breathing room. With...

Each of the many process technologies that can be used for RF power amplifiers - GaAs HBT, PHEMT, InGaP HBT and silicon RF MOSFET - have different advantages, such as better frequency characteristics, wider linearity and higher power capability. A fundamental comparison of the different process technologies is shown...
