ALM-GN001

ALM-GN001 GNSS Filter-LNA Front-End Module Data Sheet Description Avago Technologies’ ALM-GN001 is an ultra low-noise GNSS front-end module that combines a low-noise amplifier (LNA) with a GNSS FBAR pre-LNA filter. The LNA uses Avago Technologies’proprietary GaAs Enhancementmode 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 low-power GNSS applications or during low-battery situations.
