Microwave sensors are increasingly finding commercial applications, particularly in the automotive industry. Here, advanced features are used to distinguish vehicles, while safety is a major consideration in new car purchases. Therefore, it is not surprising that radar technology has been adopted and implemented in adaptive cruise control (ACC) systems....

Electromechanical distribution systems (switch matrices) are used in both commercial applications and military systems. Computer control of these switch matrices facilitates their use in automated testing and in those systems requiring remote control of switching functions. The newest product in Dow-Key's line of electromechanical switches is a single-pole 12-throw...

In today's age of high speed Internet, high frequency wireless and wireline communications, conventional materials are reaching their performance limits. Copper-based electrical connections are being limited by the dielectric properties of the insulating layer. Solutions using optical connections are available but are too expensive. Liquid crystalline polymers (LCP) are...

As the environments in which cell sites are located becomes more constricted, designers of base stations for third-generation networks are faced with challenges such as increased functional integration and other size-reduction techniques similar to those of their mobile phone counterparts. The model FEU-WCDMA1 is a W-CDMA RF front end...

Quadrifilar helical antennas (QFHA) are one of the best candidates to provide a high gain, shaped beam with excellent circular polarization axial ratio for satellite radio and mobile satellite phone systems. One of the most compelling reasons to use these antennas for digital radio and mobile satellite systems is...

Phased array antennas are traditionally used to produce narrow beams from large apertures. In this mode of operation, every radiating element in the array is broadly co-phased. The radiation pattern of the antenna is then the product of both the individual radiating element characteristic pattern and the array factor....

Optical networking and its supporting equipment, components and integrated circuits (ICs) are heading toward a market windfall, according to In-Stat/MDR. The high tech market research firm reports that with the geometric growth of the Internet, private IP networks and business-to-business (B2B) e-commerce, the demand for high speed capacity, within...

Isat 903, the latest in a line of advanced communications satellites built for Intelsat by Space Systems/ Loral (SS/L), a subsidiary of Loral Space and Communications, was successfully launched on March 30, 2002. The satellite was sent into space from the Baikonur Cosmodrome in Kazakhstan, aboard an ILS Proton...

According to In-Stat, the Optical Fiber Conference (OFC) held in Anaheim, CA, in March, was much quieter than last year's - a real reflection of the dismal market conditions in the telecom sector right now - and the fact that the tremendous hype surrounding the use of MEMS in...

As evidenced by CeBIT and CITA, Bluetooth solutions continue to make strides. Many products have been first launched in Europe and/or Asia, as many vendors consider the North American market to be behind. However, many companies realize that unless they also make their products available to North America, they...
