MAX2688：GPS/GNSS Low-Noise Amplifiers

Low-Noise-Figure GPS LNAs in an Ultra-Small WLP Package Offer Versions with Different Levels of Gain

The MAX2686/MAX2688 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 ultra-low-noise figure while maximizing the input-referred 1dB compression point and the 3rd-order intercept point. The MAX2686 provides a high gain of 19dB. The MAX2688 supplies 15dB of gain while attaining higher linearity. The devices operate from a +1.6V to +3.3V single supply. The optional shutdown feature in the devices reduces the supply current to less than 10µA. The devices are available in a very small, lead-free, RoHS-compliant, 0.86mm x 0.86mm x 0.65mm wafer-level package (WLP).
