EVALUATION KIT AVAILABLE MAX2667/MAX2669 GPS/GNSS Ultra-Low-Noise-Figure LNAs General Description Features The MAX2667/MAX2669 high-gain, low-noise amplifiers S 19dB High-Power Gain (MAX2667) (LNAs) are designed for GPS L1, Galileo, and GLONASS S Ultra-Low Noise Figure: 0.65dB applications. Designed in Maxims advanced SiGe pro- S Integrated 50 Output Matching Circuit cess, the devices achieve a high gain and our lowest S Low 4.1mA Supply Current (MAX2667) noise figure, while maximizing the input-referred 1dB compression point and the 3rd-order intercept point. S Wide 1.6V to 3.3V Supply Voltage Range The devices operate from a +1.6V to +3.3V single sup- S Low Bill of Materials: Two Inductors, Three ply. The MAX2667 is optimized for low current. The Capacitors, and One Resistor MAX2669 is optimized for high linearity. The shutdown S Small Footprint: 0.86mm x 1.26mm feature in the device reduces the supply current to be S Thin Profile: 0.65mm less than 10A. The devices are available in a very small, lead-free, RoHS-compliant, 0.86mm x 1.26mm x 0.65mm S 0.4mm-Pitch Wafer-Level Package (WLP) 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 operation 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.
