EVALUATION KIT AVAILABLE MAX2686L/MAX2693L GPS/GNSS Low-Noise Amplifiers with Integrated LDO General Description Benefits and Features The MAX2686L/MAX2693L low-noise amplifiers (LNAs) High Power Gain: 19dB (MAX2686L) are designed for GPS L1, Galileo, and GLONASS applica- Low Noise Figure: 0.88dB (MAX2686L) tions. Designed in Maxims advanced SiGe process, the Integrated 50 Output Matching Circuit devices achieve high gain and low noise figure while maxi- mizing the input-referred 1dB compression point and the Low Supply Current: 1.8mA (MAX2693L) 3rd-order intercept point. Both devices include an internal Wide Supply Voltage Range: 1.6V to 4.2V LDO ideal for battery-powered applications. For current- Low Bill of Materials: One Inductor, Two Capacitors sensitive applications, the MAX2693L achieves excellent Small Footprint: 0.86mm x 0.86mm performance while consuming only 1.8mA current. 0.4mm Pitch WLP The devices operate from a +1.6V to +4.2V single sup- ply. The shutdown feature reduces the supply current to less than 20A. The devices are available in a very small, lead-free, RoHS-compliant, 0.86mm x 0.86mm x 0.65mm wafer-level package (WLP).
