MGA-635T6

GPS Low Noise Amplifier with Variable Bias

Current and Shutdown Function

Data Sheet

Description

Avago Technologiesâ MGA-635T6 is a LNA designed

for GPS/ISM/Wimax applications in the (0.9-2.4)GHz

frequency range. The LNA uses Avago Technologiesâs

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 pa-

rameters. A CMOS compatible shutdown pin is included

to turn the LNA off and provide a variable bias.

The MGA-635T6 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.
