Description
Avago Technologies’ ALM-2712 is an ultra low-noise GPS
front-end module that combines a low-noise amplier
(LNA) with GPS FBAR lters. The LNA uses Avago Tech-
nologies’ proprietary GaAs Enhancement-mode pHEMT
process to achieve high gain with very low noise gure
and high linearity. Noise gure distribution is very tightly
controlled. A CMOS-compatible shutdown pin is included
either for turning the LNA on/o, or for current adjust-
ment. The integrated lter utilizes an Avago Technologies’
leading-edge FBAR lter for exceptional rejection at
Cellular, DCS, PCS and WLAN band frequencies. Bypass
functionality with an external RF switch is possible with
separate RF switching.
The low noise gure and high gain, coupled with low cur-
rent consumption make it suitable for use in critical low-
power GPS applications or during low-battery situations.
