MAX2678 GPS/GNSS Front-End Amplifier IC Analog Devices 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 the receiver. Two unconditionally stable low-noise amplifier stages provide the high gain and integrated I/O matching. These stages minimize the need for external matching components and eliminate the need for additional gain stages.
