Sprint Nextel has signed nine partners to help it roll out bleeding-edge subscriber location services. Based on XOHM WiMAX technology, Sprint’s high-speed mobile data network will turn up commercial service in Baltimore this September (see Sprint to launch first WiMAX service in Baltimore ), with more cities — likely...

Agilent Technologies Inc. announced the industry's first Digital Radio Frequency (DigRF) V4 test solution . It enables comprehensive stimulus and analysis for developers of radio-frequency integrated circuits (RF-IC) and baseband ICs (BB-IC) as well as integrators of wireless handsets. DigRF V4, driven by the MIPI (Mobile Industry Processor Interface)...

Sprint and Clearwire may grab most of the US WiMAX headlines, but there is growing uptake of the technology among smaller operators using the new lightly licensed 3.65GHz band, and this may support a more attractive business model than the last system for delivering disruptive open wireless services, metro...

Worldmax , a competitive WiMAX operator in the Netherlands, is utilizing Ceragon Networks’ FibeAir® IP solutions in one of Europe’s first commercial WiMAX networks. With this deployment Worldmax joins more than 40 WiMAX operators and service providers worldwide who are using Ceragon’s solutions for high-capacity backhaul applications. The solution...

SiGe Semiconductor Inc. announced the availability of the SE2597L power amplifier (PA) designed specifically for 2.4 GHz ISM band applications. This highly integrated silicon device is the latest PA in SiGe Semiconductor's successful line of discrete 2.4 GHz silicon power amplifiers. Offering an industry-leading combination of high performance and...

This is the first European Wireless Technology (EuWiT) Conference . It was formerly known as the European Conference on Wireless Technology (ECWT) . Co-sponsored by Eu M A and the IEEE MTT Society, EuWiT is an integral part of European Microwave Week and is a forum for the presentation...

From its conception in 1943 by Dr. Rudolf Kompfner in England, 1 and later its development by Kompfner and John R. Pierce at the Bell Laboratories in the United States, 2 the travelling wave tube (TWT) has become the microwave amplifier of choice for many commercial and military systems....

The transceiver duplexer is a key element in avionics systems, radars, antenna arrays and wireless communication systems. The duplexer provides protection of the receiver and transmitter from unwanted parasitic signals. This article discusses several duplexer schematics, their development flow and a trade-off design. Duplexer Schematics An RF transceiver duplexer...

Part I of this report last month focused on individual countries and their contributions and achievements related to the microwave industry. But the continent as a whole plays a key role in all sectors including industrial, biomedical, military, aerospace and emerging wireless technologies. Since there is such a broad...

This six-part series looks at five decades of the microwave industry recorded in Microwave Journal . In this fourth installment, we focus on the 1980s, a decade marked by such notable events as the birth of MTV, punk rock and “new wave,” the marriage of Prince Charles and Diana,...
