MAX2691
L2 Band GPS Low-Noise Amplifier
General Description
The MAX2691 low-noise amplifier (LNA) is designed for
GPS L2 applications. Designed in Maxim’s advanced
SiGe process, the device achieves high gain and
low noise figure while maximizing the input-referred 1dB
compression point and the 3rd-order intercept point. The
MAX2691 provides a high gain of 17.5dB and sub 1dB
noise figure.
The device operates from a +1.6V to +3.6V single sup-
ply. The optional shutdown feature in the device reduces
the typical supply current to 4FA. The device is available
in a very small, lead-free, RoHS-compliant, 0.86mm x
0.86mm x 0.65mm wafer-level package (WLP).
