ALM-2412

GPS LNA-Filter Front-End Module

Data Sheet

Description

Features

 Very Low Noise Figure : 0.85 dB typical

 High Gain : 13.5 dB typical

 High IIP3 and IP1dB

 Exceptional Cell/PCS-Band rejection

 Advanced GaAs E-pHEMT Technology

 Low external component count

 Wide Supply Voltage : 1V to 3.6V

 Shutdown current : < 0.1uA

Avago Technologies’ ALM-2412 is an LNA module, with

integrated ﬁlter, designed for GPS band applications at

1.575GHz. The LNA uses Avago Technologies’ proprietary

GaAs Enhancement-mode pHEMT process to achieve high

gain with very low noise ﬁgure and high linearity. Noise

ﬁgure distribution is very tightly controlled. A CMOS-com-

patible shutdown pin is included either for turning the

LNA on/oﬀ, or for current adjustment. The integrated ﬁlter

utilizes an Avago Technologies’ leading-edge FBAR ﬁlter

for exceptional rejection at Cell/PCS-Band frequencies.

 CMOS compatible shutdown pin (SD) current @ 2.8V :

The ALM-2412 is useable down to 1V operation. It achieves

low noise ﬁgure, high gain and linearity even at 1V, making

it suitable for use in critical low-power GPS applications or

during low-battery situations.

0.1mA

 Adjustable current via single external resistor/voltage

 Meets MSL3, Lead-Free and Halogen-Free

 ESD-protected RF input: 3kV HBM
