General Description
Features
The MAX2692/MAX2695 low-noise amplifiers (LNAs) are
designed for WLAN/WiMAX applications. Designed
in Maxim’s advanced SiGe process, the devices
achieve high gain and low noise figure while maximizing
3rd-order intercept point.
S 2.5GHz WLAN (MAX2692)
M
S 3.7GHz WiMAX (MAX2695)
S High-Power Gain: 18dB (MAX2692)
S Low Noise Figure: 1.1dB (MAX2692)
S High-Input-IP3: -3dBm (MAX2695)
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).
S Integrated 50Ω Output Matching Circuit

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.

The MAX2692/MAX2695 are LNAs designed for WLAN/
WiMax applications. The devices feature an optional

Input and Output Matching
The devices require an off-chip input matching. Only an
inductor in series with a DC-blocking capacitor is needed
to form the input matching circuit. The Typical Operating
