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 supply. The optional shutdown feature in the device reduces the typical supply current to 4µA. The device is available in a very small, lead-free, RoHS-compliant, 0.86mm x 0.86mm x 0.65mm wafer-level package (WLP).
