MGA-635T6

GPS Low Noise Ampliﬁer with Variable Bias

Current and Shutdown Function

Data Sheet

Description

Features

 Low Noise Figure : 0.74dB

Avago Technologies’ MGA-635T6 is a LNA designed

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

frequency range. The LNA uses Avago 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 pa-

rameters. A CMOS compatible shutdown pin is included

to turn the LNA oﬀ and provide a variable bias.

 High Gain : 14.5dB

 High linearity and P1dB

 GaAs E-pHEMT Technology

 Low component count

 Wide Supply Voltage : 1V to 3.6V

 Shutdown current : < 0.1uA

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.

 CMOS compatible shutdown pin (VSD) current @

2.85V : 60uA

 Adjustable bias current via one single external resis-

tor/voltage

Surface Mount 2.0x1.3x0.4 mm 6-lead UTSLP

 Small Footprint: 2 x 1.3mm

 Low Proﬁle : 0.4 mm

 Ext matching for non-GPS freq band operation
