MGA-231T6
High-Gain GPS LNA
with Variable Current and Shutdown Function
Data Sheet
Description
Avago Technologies’ MGA-231T6 is a low-noise amplifier
(LNA) designed for GPS/ISM/Wimax applications in the
(0.9-3.5)GHz frequency range. The LNA uses Avago Tech-
nologies’ 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-compatible shutdown pin is included
either for turning the LNA on/off or for current adjust-
ment.
The low noise figure and high gain, coupled with low cur-
rent consumption make it suitable for use in critical low-
power GPS applications or during low-battery situations.
