Avago Technologies Simplifies GPS Designs With First Complete GPS RF Front End Module With FBAR Filters -- GPS Low Noise Amplifier With Integrated Filters Ideal for S-GPS, Superior Performance and Small Form Factor Designs
SAN JOSE, Calif.--Avago Technologies, a leading supplier of analog interface components for communications, industrial and consumer applications, today 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.
Pricing and Availability
Products will be available in December 2008. Pricing for the ALM-1712 begins at $1.81 in the 10,000 piece quantity range.
