Analog Devices / Maxim Integrated MAX2659 GPS/GNSS Low-Noise Amplifier Chip
Analog Devices MAX2659 GPS/GNSS Low-Noise Amplifier is a high-gain, low-noise amplifier (LNA) that is designed for GPS, Galileo, and GLONASS applications. Designed in Maxim's advanced SiGe process, the device achieves a 20.5dB gain and an ultra-low-noise figure of 0.8dB. This is done while maximizing the input-referred 1dB compression point and the 3rd-order intercept point at -12dBm and -5dBm, respectively. The MAX2659 operates from a +1.6V to +3.3V single supply and consumes only 4.1mA. The shutdown feature in the device reduces the supply current to be less than 1µA. The Analog Devices MAX2659 GPS/GNSS Low-Noise Amplifier is available in a compact 1.5mm x 1.0mm μDFN package.
