• Intro to Satellite Radio
  and the sometimes limited availability of coverage. Transmission of the satellite signal passes through a specially designed Antenna to an RF Receiver, and then passed through to the Tuner module installed inside the car. Amphenol RF offers a wide range of inter-connect solutions for the satellite...
• Smart Materials Provide For Self-Adjusting Satellite Antennas
  the direction of standard antennas, they create inertial forces that throw off the orientation of the entire satellite. But an adjustable antenna with actuators made of plastic and piezoceramic material would be light enough to generate very little inertia. That s one of the significant benefits...
• PM Brings Satellite TV to RVs
  while parked. When the unit powers on, it unfolds from a 10-in.-tall stowed position on the vehicle's roof. The antenna automatically points at the appropriate geostationary satellite by adjusting rotation, elevation, and skew. Winegard engineers reviewed various options for gears and bearings...
• Tilting at satellites
  the antenna with the appropriate satellite. Combined with digital electronics, full ESD and EMI protection, and an aluminum housing, the entire assembly is encased in an epoxy-based potting compound for environmental protection. The Spectrotilt RS-232 electronic inclinometer features an accuracy of +-0.3...
• Flatter reducer makes waves
  the width of the company's previous CSF design, yet retains 70% of the rated torque. It's also 20% lighter per rated torque and consumes 27% less volume. Developers say these attributes make CSDs attractive for next-generation satellite solar-array drives, antenna pointers, as well as precision robots...
• Intermodulation Distortion in RF Connectors
  on the transmit side usually between the diplexer and the antenna. With no filtering on these transmission paths, the distorted signals made their way to the receive end. With improved materials, technology and test equipment, solutions for reducing the effects are now possible. Technical Information...
• What's hot in consumer electronics
  to influence the consumer electronics industry in the year ahead. First, cheaper HDTV sets and more HD programming will spur demand for such as Blu-Ray Disc, HD-DVD and HD-DVR. About 10% of American homes have digital video recorders and that number is expected to climb next year as more cable and satellite...
• Thin Film Resonators and High Frequency Filters
  in the spectrum from 500 MHz to 6 GHz. These systems include pager, cellular phone, navigation, satellite communication, and various forms of data communication. Other electronic systems have need for frequency control devices beyond 6 GHz. The need for high performance frequency control devices has become...
• 100 years of flight - Keep them flying : Avionics
  miles away.) To get around this limitation, engineers developed HF radio (short wave) that peeked over the horizon by bouncing off the ionosphere. Another solution to the line-of-sight problem is to mount the radar antenna as high as possible. This approach, and the trend toward ever smaller electronic...

  to form a digitally-controlled antenna with digital output for Global Positioning Satellite systems. Bombing expected to shape export debate U.S. export controls on dual-use technologies could be tightened as a result of this week's terrorist attacks, but at least one expert said the tragedy...
