ALM-2412
GPS LNA-Filter Front-End Module
Data Sheet
Description
Avago Technologies’ ALM-2412 is an LNA module, with
integrated filter, designed for GPS band applications at
1.575GHz. 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-com-
patible 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 ALM-2412 is useable down to 1V operation. It achieves
low noise figure, high gain and linearity even at 1V, making
it suitable for use in critical low-power GPS applications or
during low-battery situations.
