Avago Technologies Simplifies GPS Designs
San Jose CA (SPX) Nov 27, 2008 Avago Technologies has announced a highly integrated GPS low noise amplifier (LNA) with high performance levels. The ALM-1712 effectively integrates a sophisticated GPS LNA and two FBAR filters. This results in a complete, compact and high-performance GPS RF front end module that simplifies the design of a wide range of GPS applications. Simultaneous GPS, and other location-based GPS services, requires a high level of receiver sensitivity. Avago's ALM-1712 is a complete GPS RF front end that delivers very low noise figures, high linearity and superior out-of-band rejection performance. By integrating a GPS LNA with pre and post high-rejection FBAR (film bulk acoustic resonator) filters, the high-performance ALM-1712 simplifies and shortens the RF design process, reduces component count and provides excellent RF performance levels that are critical in the use of GPS applications. Avago's highly integrated ALM-1712 is housed in a miniature 4.5 x 2.2 x 1.0 mm MCOB package, reducing PCB space by more than 50% when compared to a discreet-only solution. The integration of FBAR filtering enables the ALM-1712 to reach more than 85 dBc of cell/PCS-band rejection levels. Additionally, the ALM-1712 effectively leverages Avago's 0.5 um GaAs enhancement-mode pHEMT process to deliver a 1.7 dB noise figure, 13.5 dB gain, and +5 dBm IIP3 (input third order intercept point) at typical operating condition of 2.7V and 8 mA. At low voltages down to 1.8V, the module can still achieve very low noise figure and high linearity, which makes it very suitable for use in low-power GPS applications. The ALM-1712 is designed for the 1.575 GHz frequency band, targeting handset GPS, recreational and in-vehicle GPS receiver and GPS antenna applications.

Local Election Processes Improved With ESRI GIS
Redlands CA (SPX) Nov 27, 2008The Registrar of Voters (ROV) of Alameda County, California, used ESRI's geographic information system (GIS) software to simplify precinct analysis and polling station siting processes during the 2008 election. The ROV's GIS-streamlined processes saved the department time, money, and labor hours and improved customer service. |
