MAX2693L:GPS/GNSS Low-Noise Amplifiers with Integrated LDO

Low-Noise-Figure GPS LNA in an Ultra-Small WLP; Versions Available with Different Levels of Gain

The MAX2686L /MAX2693L low-noise amplifiers (LNAs) are designed for GPS L1, Galileo, and GLONASS applications. Designed in Maxim’s advanced SiGe process, the devices achieve high gain and low noise figure while maximizing the input-referred 1dB compression point and the 3rd-order intercept point. Both devices include an internal LDO ideal for battery-powered applications. For current-sensitive applications, the MAX2693L achieves excellent performance while consuming only 1.8mA current. The devices operate from a +1.6V to +4.2V single supply. The shutdown feature reduces the supply current to less than 20µA. The devices are available in a very small, lead-free, RoHS-compliant, 0.86mm x 0.86mm x 0.65mm wafer-level package (WLP).
