ALM-1612
GPS LNA-Filter Front-End Module
Data Sheet
Description
Features
Avago Technologies’ALM-1612 is a GPS front-end module Very Low Noise Figure: 0.95 dB typ.
that combines a low-noise amplifier (LNA) with a GPS FBAR
filter. The LNA uses Avago Technologies’ proprietary GaAs
Enhancement-mode pHEMT process to achieve high gain
High Gain: 18.2 dB typ.
High IIP3 and IP1dB
with very low noise figure and high linearity. Noise figure Exceptional Cell/PCS-Band rejection
distribution is very tightly controlled. A CMOS-compat-
ible shutdown pin is included either for turning the LNA
on/off, or for current adjustment. The integrated filter
Advanced GaAs E-pHEMT & FBAR Technology
Low external component count
utilizes an Avago Technologies’ leading-edge FBAR filter Shutdown current: < 5 uA
for exceptional rejection at Cell/PCS-Band frequencies.
CMOS compatible shutdown pin (SD) current @ 2.7 V:
0.1mA
The low noise figure and high gain, coupled with low
current consumption make it suitable for use in critical low-
power GPS applications or during low-battery situations.
ESD: For RFin (Pin 3): ESD Human Body Model > 3kV;
All other pins: ESD Machine Model = 70V, ESD Human
Body Model = 300V
