射频放大器 GPS/GNSS Front-End Amplifier

The is a GPS/GNSS front end amplifier in 10 pin TDFN package. This 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 antenna to receiver. Two unconditionally stable low noise amplifier stages provide high gain and integrated I/O matching to minimize need for external matching components and eliminate need for additional gain stages. The device 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/GNSS receiver. Additionally, a 3.4dB gain step is provided to compensate for cable loss variation between different applications. It is used in integrated automotive and marine GPS receivers and active antennas.
