m o c Agilent ALM-1106 GPS Low Noise amplifier with Variable bias current and Shutdown function Data Sheet Features Simplified Schmatic VSD VDD • Advanced GaAs E-pHEMT Description Agilent Technologies’s ALM1106 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.
