Now celebrating its 32nd edition, RF & Hyper Europe 2006 will, for the first time, be organized by Exposium's Industry, Commerce & Technologies department that has taken over from BIRP. Growth, especially on the international front, is expected for the event, which will showcase the technological innovations of some...

Sirenza Microdevices Inc. announced a definitive agreement to acquire Premier Devices Inc. (PDI) for a combination of common stock, cash and debt valued at approximately $72.1 M. PDI designs, manufactures and markets complementary RF components featuring technologies common to existing and planned Sirenza products. With this acquisition, Sirenza, a...

DesignAdvance™ Systems Inc. , an electronic design automation (EDA) and computer aided design (CAD) design-synthesis software developer, announced that it has completed a $3 M second round of funding and has graduated from The Technology Collaborative's Jumpstart program. "We have a field proven solution for PCB design and are...

The ‘information age’ has seen the significant emergence of wireless applications mainly dedicated to improving the quality of people’s lives (especially disabled and senior citizens), improving health, increasing the efficiency of air and road traffic, and bettering the environment. Over the last twenty years there has been a radical...

This article presents the design of a 3.3 to 3.8 GHz LNA, suitable for IEEE 802.16a WiMAX customer premise equipment (CPE) and base transceiver stations (BTS), built on inexpensive FR4 copper laminate epoxy glass board material using the Agilent Technologies ATF-54143 E-pHEMT (enhancement-mode pseudomorphic high electron mobility transistor). The...

Recently, more attention has been paid to applications of ultrawideband (UWB) technology on wireless communication. It offers advantages of decreased cost and increased capabilities, compared with other conventional radio technologies. Standards activities for UWB systems are promoting a global perspective for not only technology but also regulations. UWB has...

This article presents the design approach and test results of 1, 1.5, 2 and 5 W, Ku-band MMIC power amplifiers developed using the high performance MSAG MESFET technology. Both single-ended and balanced topologies were used. A minimum power-added efficiency (PAE) of 27 percent, an output power (P out )...

Photonic band-gap (PBG) structures were initially proposed in the optical component field. In the microwave field, PBG periodic structures suppress the propagation of electromagnetic waves whose frequencies are within certain bands. They allow shifting the rejected frequency band by simply changing the geometry parameters of the PBG element or...

A coupler with a through loss of less than 1.45 dB from 5 to 900 MHz was needed in a 75 ? system and only commercial couplers of 10 dB (or more) could offer this low through loss, particularly at the highest frequencies. Unfortunately, another requirement was to produce...

In 1965, inhabitants of Salvan, Switzerland, located above Martigny in the Mont Blanc region, “remembered” that a senior citizen of their village had lived a very unusual experience seventy years before, when he was a young boy.
