The MAX2678 GPS/GNSS front-end amplifier IC is designed for automotive and marine GPS/GNSS satellite navigation antenna modules, or for any application that needs to compensate for cable losses from the antenna to receiver. Two unconditionally stable low-noise amplifier stages provide the high gain and integrated I/O matching to minimize the need for external matching components and eliminate the need for additional gain stages. The IC features the option to place a bandpass ceramic or surface acoustic wave (SAW) filter between the two amplifier stages for improved immunity to out-of-band interferers.
