MAX2689:GPS/GNSS Low-Noise Amplifiers

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

The MAX2687/MAX2689/MAX2694 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. The MAX2687/MAX2689/MAX2694 provide high gains of 12dB, 15dB, and 18dB, respectively. Each is optimized for high linearity. 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 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).
