Overview
ALM-2712 GPS Filter-LNA-Filter Front-End Module Data Sheet Description Avago Technologies’ ALM-2712 is an ultra low-noise 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 Cellular, DCS, PCS and WLAN band frequencies.
Bypass functionality with an external RF switch is possible with separate RF switching.
The low noise figure and high gain, coupled with low current consumption make it suitable for use in critical lowpower GPS applications or during low-battery situations.
