ALM-3012 GNSS LNA-Filter Front-End Module with optional Differential Outputs Data Sheet Description Avago Technologies’ ALM-3012 is an ultra low-noise GNSS (Global Navigation Satellite System) front-end module that combines a low-noise amplifier (LNA) with a GNSS FBAR post-LNA filter, supporting both GPS and GLONASS operating in 1565 ~ 1606 MHz frequency range. The module can be used both as a single-ended and pre-matched differential outputs. 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.
