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 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).
