MAX2692/MAX2695
WLAN/WiMAX Low-Noise Amplifiers
General Description
The MAX2692/MAX2695 low-noise amplifiers (LNAs) are
designed for WLAN/WiMAX
M
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 avail-
able in a very small, lead-free, RoHS-compliant, 0.86mm
x 0.86mm x 0.65mm wafer-level package (WLP).

CAUTION!
ESD SENSITIVE DEVICE
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional opera-
tion of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
