The MAX2657/MAX2658 high-gain, low-noise amplifiers
(LNAs) are designed for GPS L1, Galileo, and
GLONASS applications. Designed in Maxim’s
advanced SiGe process, the devices achieve a high
gain and an ultra-low-noise figure while maximizing the
input-referred 1dB compression point and the 3rd-order
intercept point.
The MAX2657/MAX2658 operate from a +1.6V to +3.3V
single supply. The MAX2657 is optimized for low current.
The MAX2658 is optimized for high linearity. The shut-
down feature in the device reduces the supply current to
be less than 1µA. The MAX2657/MAX2658 are available
in a very small, lead-free, RoHS-compliant, 0.86mm x
1.26mm x 0.65mm, wafer-level package (WLP).
