Integrated RF Front End for RFID and Unlicensed UHF ISM Band Applications
High performance RFID readers typically require many expensive discrete RF components to achieve the level of performance necessary in a dense reader environment.
To address this need, the ADF9010 reduces component count, board space, and design time with its fully integrated RF Tx modulator and Rx analog baseband for applications that operate in the 900 MHz frequency range. The ADF9010 integrates a high performance Tx quadrature modulator with an integer-N synthesizer and an on-chip, low phase noise voltage controlled oscillator (VCO) to maintain superb RF performance and lower system cost. When used in an RFID application, for example, the combination of integration and performance featured in the ADF9010 can result in a bill-of-material savings of as much as 50% and board space reductions up to 70%, as well as a substantial reduction in design cycle time as compared to a multiple discrete component approach. Applications include RFID readers; industrial, scientific, and medical (ISM) band radio communications devices; professional mobile radios; cellular base stations; and RF-over-coax applications.

Blackfin Processors Enable Precision Inspection, Alignment, and Repair of High Speed Rails for Safer and More Cost-Effective Travel
Motivated by shorter travel times and a comfortable ride, passengers are increasingly taking advantage of high speed rail travel. The high speeds and associated accelerations expose both the rail cars and the rails to extreme mechanical stress. This stress accelerates rail defects over time, requiring vigilant monitoring and inspection to ensure a safe and smooth ride, as well as to avoid costly unscheduled infrastructure upgrades.
The ADI Blackfin® processor-based rail monitoring system accurately measures and records track spacing, tilt, profile of the wheel contact surface, and track surface conditions. Five separate Blackfin processors work in harmony to help coordinate vital subsystems, such as keyboard/TFT monitor interfaces, and track geometry profiles and related GPS location information. They also handle data filtering functions and data storage that is captured in the on-board RAM buffers and written to the convenient and robust removable media.
These stored rail geometry parameters and GPS data are downloaded into a common software platform that links the geometry, profile, and surface condition with location and odometer information at an off line maintenance IT facility. The result is a true digital representation of the entire rail system. The resulting maintenance plan is downloaded into the maintenance machines that perform the required track repair. A dual Blackfin processor locates and controls the repair of worn-out or defective rail sections quickly and systematically. After the repair process is complete, measuring the profiles of the repaired section and loading it into the digital database assures quality.
