Semiconductor manufacturing in Asia has been increasing at an impressive pace and that trend will continue for at least the next several years, reports In-Stat. Asian semiconductor-manufacturing capacity will increase at a compound annual growth rate of 10.8 percent from 2006 to 2011, the high-tech market research firm says....

Wireless LAN (WLAN) technology has become a standard part of business networks, and portable computers with Wi-Fi and inexpensive wireless routers have made connectivity even more pervasive outside of the business premises, reports In-Stat. These trends, and growth in the Wi-Fi phone market, pose key security challenges for IT...

Mobile video messaging services are at the center of the technology convergence that is helping mobile customers realize greater levels of self-expression and on-line community participation. This according to Dan Shey, principal analyst at ABI Research. “Mobile video messaging is perfectly positioned to take advantage of the convergence of...

Industry News Dielectric Communications , a division of SPX and a developer of broadcast antenna systems, announced that the National Academy of Television Arts and Sciences will present the company with a Technology and Engineering Emmy® Award at an awards ceremony during the International Consumer Electronics Show (CES) in...

Today’s handsets have to meet tough technical requirements. Mobile phones have to deal with an ever-increasing number of services, while at the same time the cost of the systems is being reduced. R&D in the mobile phone industry copes with this situation by continuously improving the mobile phone efficiency...

Variations in semiconductor manufacturing technology are unavoidable; therefore, the IC must be designed for yield even at the extremes of process variation. The goal of statistical and corner models is accurate simulation of the process-induced variation of circuit performances, such as gain-bandwidth products, distortion levels and phase noise. Process...

Many microwave radar transmitters require active devices that can produce RF output power in the order of kilowatts to even megawatts. Routinely, microwave traveling-wave tube devices are utilized for this application. However, the currently used traveling-wave tubes are inefficient, large, expensive and have suspect reliability. While semiconductor-based amplifiers in...

During take off and landing flight phases, helicopters can encounter serious brown-out or white-out problems in dusty, sandy or snowy areas as the downwash of the rotor blades creates dust clouds that can completely engulf the helicopter. This is graphically illustrated in Figure 1 . During landing in particular,...

Along with monopole, patch and slot antennas, the inverted-F antenna (IFA) has become of primary importance for portable and handheld wireless communication units. It is known as a high-efficiency, quasi-omni-directional antenna, with a height of approximately 0.05 to 0.1λ, which is 2.5 to 5 times shorter than a quarter-wave...

Some methods of antenna modeling and measurement lead directly to radiation patterns and total radiated power without the intermediate, and often tedious or impractical, step of calculating self and mutual impedances. 1 Still, it is often desirable and necessary to know the input impedance for each element in the...
