ALM-GA001

ALM-GA001 High-Gain, Low Current Low Noise Amplifier with Variable Current and Shutdown Function Data Sheet Description Avago Technologies’ ALM-GA001 is a low-noise amplifier (LNA) designed for GPS/ISM/WiMAX applications in the (0.9-3.5) GHz frequency range. 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 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 operation.
