The MAX12000 GPS front-end amplifier IC is designed for automotive and marine GPS satellite navigation antenna modules or for any application that needs to compensate for cable losses from the GPS 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 MAX12000 features the option to place a bandpass ceramic or SAW filter between the two amplifier stages to provide a narrow-band output to further improve the noise performance of the GPS receiver. Additionally, a 3.4dB gain step is provided to compensate for cable loss variation between different applications.
