ALM-1712
GPS Filter-LNA-Filter Front-End Module
Data Sheet
Description
Avago Technologies’ ALM-1712 is a GPS front-end module
that combines a low-noise amplifier (LNA) with GPS FBAR
filters. The LNA uses Avago Technologies’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 adjustment. The integrated filter
utilizes an Avago Technologies’ leading-edge FBAR filter
for exceptional rejection at Cell/PCS-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.
