The simplest quarter-wavelength, multi-port power divider, known as a Wilkinson divider, 1-2 provides a match at all ports, low loss, in-phase power splitting and high isolation between output ports. Historically, this device was reported earlier. 3-7 It was also described 5 together with the so-called Gysel-type combiner, 8 based...

A recently completed study by In-Stat/MDR finds that wireless data adoption is growing in the business environment - just not with the "hockey-stick" growth curve that continually has been projected. The high tech market research firm's study, which was based on more than 1500 surveys with IT decision makers...

With the absence of a currently available and standardized wireless technology that offers robust multimedia transport of multiple digital streams, Ultra-wideband (UWB) promises to be the technology that delivers the bandwidth and QoS that many consumer electronics companies have been looking for. In-Stat/MDR reports that, having seen the gap...
