MAX2692/MAX2695

WLAN/WiMAX Low-Noise Amplifiers

General Description

The MAX2692/MAX2695 low-noise amplifiers (LNAs) are designed for WLAN/WiMAXM applications. Designed in Maxim’s advanced SiGe process, the devices achieve high gain and low noise figure while maximizing 3rd-order intercept point.

The devices operate from a +1.6V to +3.6V single supply. The optional shutdown feature in the devices reduces the supply current to less than 10FA. The devices are available in a very small, lead-free, RoHS-compliant, 0.86mm x 0.86mm x 0.65mm wafer-level package (WLP).
