The MAX2670 GPS/GNSS front-end amplifier IC isdesigned for automotive and marine GPS/GNSS satellitenavigation antenna modules or for any application thatneeds to compensate for cable losses from the antennato receiver. Two unconditionally stable low-noise amplifierstages provide the high gain and integrated I/O matchingto minimize the need for external matching componentsand eliminate the need for additional gain stages. Thedevice features the option to place a bandpass ceramicor SAW filter between the two amplifier stages to providea narrow-band output to further improve the noise performanceof the GPS/GNSS receiver. Additionally, a 3.4dBgain step is provided to compensate for cable loss variationbetween different applications.
