Avago's ALM-1912 integrates a LNA and a high-rejection pre-filter in a miniature compact package to provide a complete and compact high-performance GPS radio frequency (RF) front-end module that can help to simplify the design of a wide range of GPS handset applications.
Avago's ALM-1912 is designed for use in mobile handsets, personal navigation devices (PND (Personal Navigation Device) A portable GPS-based navigation system that can be used when walking, hiking or in any vehicle. See GPS. ) and other GPS-enabled applications. This GPS front-end module is housed in a miniature 2.9 by 2.0 by 1.0 mm MCOB MCOB Multi-Chip on Board (semiconductor technology)

The integration of FBAR pre-filtering in the ALM-1912 enables the module to provide exceptional rejection at Cell, PCS (1) (Personal Communications Services) Refers to wireless services that emerged after the U.S. government auctioned commercial licenses in 1994 and 1995.

Additionally, this GPS front-end module effectively leverages Avago's 0.25 om GaAs enhancement-mode pHEMT process to deliver a 1.62 dB noise figure, 19.3 dB gain, and +1.5 dBm input third order intercept point (IIP IIP Investors In People

Simultaneous GPS (S-GPS) and other location-based GPS services require a high level of receiver sensitivity. Avago's ALM-1912 delivers a very low noise figure and high linearity which helps to significantly improve the sensitivity of GPS handset applications. A CMOS-compatible shutdown pin is included for turning the LNA on/off or for current adjustment. The integrated pre-filter utilizes Avago's leading-edge proprietary FBAR filtering technologies to provide exceptional rejection at Cell/PCS-band, and WiFi/Bluetooth frequencies making it an ideal solution to help enhance the performance of GPS receivers for S-GPS operation in handsets and other mobile devices.
