ALM-GP003
GPS FilterâLNA FrontâEnd Module
Data Sheet
Description
Avago Technologiesâ ALM-GP003 is a GPS front-end
module that combines a GPS FBAR filter with high-gain
low-noise amplifier (LNA).The LNA uses Avago Tech-
nologiesâ proprietary GaAs Enhancement-mode pHEMT
process to achieve high gain with very low noise figure
and high linearity. Noise figure distribution is very tightly
controlled. A CMOS-compatible shutdown pin is included
either for turning the LNA on/off or for current adjust-
ment. The filter use Avago Technologiesâ leading-edge
FBAR filter for low GPS band insertion loss and exception-
al rejection at Cellular, PCS and WLAN band frequencies.
The low noise figure and high gain, coupled with low current
consumption make it suitable for use in critical low-power
GPS applications or during low-battery situations.
