MGA-310G
GNSS Low Noise amplifier with Variable bias current
and shutdown function
Data Sheet
Description
Avago Technologies’ MGA-310G is an ultra low-noise
amplifier designed for GNSS band applications. The LNA
uses Avago Technologies’proprietary GaAs Enhancement-
mode pHEMT process to achieve high gain with very low
noise figures and high linearity. Noise figure distribution is
very tightly controlled. Gain and supply current are guar-
anteed parameters. A CMOS compatible shutdown pin is
included to turn the LNA off and provide variable bias.
The MGA-310G LNA is usable down to 1.8 V operation.
It achieves low noise figures and high gain even at 1.8 V,
making it suitable for use in critical low power GNSS band
applications.
