3.6 OFF-CHIP RF COMPONENTS
3.6.1 ALM-1412(U603:GPS LNA)
The ALM-1412 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- 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 ALM-1412 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.
