The personal navigation device (PND) market is showing signs of maturity as price points decline sharply, consolidation occurs and shipment growth slows, reports In-Stat. In addition, the increasing competition from GPS-enabled mobile phones represents the most significant threat the PND market will face. Nevertheless, stand-alone PND sales will continue...

Industry News Raytheon Co. announced that it has completed its acquisition of BBN Technologies , a leader in research and development, and provider of critical solutions for national defense and security missions. The purchase price is approximately $350 M, subject to post-closing adjustments. The transaction will not materially impact...

Magnetic resonance imaging (MRI) scans may cause harmful tissue heating in patients with active and passive implants, 1 such as pacemakers, deep brain stimulators, stents and prosthetic implants, as a result of the applied RF magnetic field (B1) of 64 MHz at 1.5T and 128 MHz at 3T. Consequently,...

There is a great deal of interest in using RF technology for cancer treatment. Research has offered hard evidence that this technology works and has advantages over traditional medical surgery. Recent research from major medical centers has prompted the observation that Radio Frequency Ablation (RFA) treatment has proven to...

Wireless Positioning Technologies and Applications Alan Bensky In many wireless systems, distance measurement and position location capabilities have become necessary. A big thrust toward this was in 1995 when the FCC started requiring 911 caller location services for cellular phones. Other applications where position location has become important include...

In the past few years, the development of In-based devices has enabled receiver systems with record noise temperatures and low power consumption. Incoming Sb-based devices promise to achieve their lowest noise at even lower power consumption. Both technologies, although not yet mature, are usually adequate for designers working with...

Recently, the demand for highly integrated and miniaturized radio frequency integrated circuits (RFIC) has increased in the wireless communication systems market. With the evolution of silicon CMOS device process technology, highly integrated silicon ICs, including RF and base-band block, have been developed. 1 However, passive components such as couplers,...

The loop test translator (LTT) is an extremely valuable tool for evaluating the performance of satellite earth stations. It allows the user to carry out analysis, alignment and testing without incurring satellite airtime costs and the risk of interfering with other satellite users. Thus, it has applications during equipment...

Radio frequency identification, or RFID, is a generic term for technologies that use radio waves to automatically identify people or objects. The purpose of an RFID system is to obtain data programmed in devices, which is then read by an RFID reader and processed for the particular application. The...
