ALM-1106

ALM-1106 GPS Low Noise amplifier with Variable bias current and Shutdown function Data Sheet Description Avago Technologies’s ALM-1106 is a LNA designed for GPS/ISM/Wimax applications in the (0.9-3.5)GHz frequency range. The LNA uses Agilent Technologies’s proprietary GaAs Enhancement-mode pHEMT process to achieve high gain operation with very low noise figures and high linearity. Noise figure distribution is very tightly controlled. Gain and supply current are guaranteed parameters. A CMOS compatible shutdown pin is included to turn the LNA off and provide a variable bias. The ALM-1106 LNA is useable down to 1V operation. It achieves low noise figures and high gain even at 1V, making it suitable for use in critical low power GPS/ISM band applications.
