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.
