The ALM-1412 is an GPS LNA front end filter module, with integrated filter, designed for GPS band application 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 utilises an Avago Technologies leading edge FBAR filter for exceptional rejection at cell/PCS band frequencies. The ALM-1412 is usable down to 1 V operation. It achieves low noise figure, high gain and linearity even at 1V, making it suitable for use in critical low-power GPS application or during low-battery situations.
