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...
