In 2008, the road to 4G has cleared a bit, with Ultra-mobile Broadband (UMB) left publicly by the roadside. However, the two remaining “4G” technologies, LTE and WiMAX, still present much speculation and confusion, InStat reported. Generally, “4G” technologies are considered those which are expected to meet the ITU’s...

The fledging market for ultra-mobile devices (UMD)—a catch-all term that includes ultra-mobile PCs (UMPC), netbooks and mobile Internet devices (MID)—is already complex and will become more complicated as it grows. A few salient forecast numbers may serve to guide vendors and investors as they negotiate this tricky landscape. According...

Driven by the still rising number of broadband subscribers, the desire to share bandwidth, residential gateway use by telecom broadband providers, and increases in Asia/Pacific, the worldwide installed base of home networks is expected to break the 200 million mark by the end of 2008. Compared to previous years,...

Industry News The Fordahl Group based in Switzerland and FOQ Piezo Technik GmbH based in Germany have signed a Management, Commercial and Technical agreement that will lead to the creation of the largest European crystal and oscillator manufacturing group. This initiative is not only aimed at strengthening Fordahl-FOQ’s activities...

Virtual Field Monitor for AR Field Probes AR’s virtual field monitor provides a graphical user interface that allows control of all probe functions, while displaying probe data and status. The probe can control up to 16 probes – any combination of AR’s battery or laser powered field probes –...

Passive and Control Components Programmable Attenuator The M-DVAN-6018-60DD-SK is a programmable attenuator that incorporates a new linearization circuit to enable fast and accurate attenuation switching. The new design focuses on quick settling and stable operation over temperature extremes. Switching between any attenuation level is typically settled within 1 dB...

At that time, many devices had been established in practical electronic systems, including signal processing devices and bandpass filters for...

Microwave Engineers: For the Sake of the Future Microwave Power Transmission: Space-based Solar Power Beams Become Next Energy Frontier The idea of using satellites to beam solar power down from space is nothing new—the Department of Energy first studied it in the 1970s, and NASA took another look in...

Many papers have been written on the theoretical design of microwave filters and the methods for computing the theoretical constants of a particular filter are known. The gap between the computation of the constants of the filter parameters and the fabrication and alignment of the filter to realize the...
