MAX2657/MAX2658
EVALUATION KIT AVAILABLE
GPS/GNSS Low-Noise Amplifiers
General Description
The MAX2657/MAX2658 high-gain, low-noise amplifiers
(LNAs) are designed for GPS L1, Galileo, and GLONASS
applications. Designed in Maxim's advanced SiGe pro-
cess, 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).
