MAXIM MAX12000 handbook
Update: 30 September, 2023
The MAX12000 is a car and ship GPS front-end amplifier IC, which has two unconditionally stable low-noise amplifier stages, providing high gain and integrated I/O matching, minimizing the need for external matching components and eliminating the need for additional gain stages. The MAX12000 provides the option to place a bandpass ceramic or SAW filter between the two amplifier stages to provide a narrow-band output, further improving the noise performance of the GPS receiver. Additionally, a 3.4dB gain step is provided to compensate for variation in cable loss between different applications. MAX12000 is designed to operate at the GPS frequency of 1575MHz with a typical cascaded gain of 34.8dB and a 25mA supply current. The two LNA stages allow the use of a wide range of GPS filter types for maximum flexibility in system design. The final RF output pin, which drives the cable to the GPS receiver, is also the power-supply connection that accepts a DC supply in the +3.0V to +5.5V range. Alternatively, the DC supply can be applied to pin 4. The GPS front-end amplifier is designed on a low-noise, advanced SiGe process and is available in a lead-free, 10-pin TDFN surface-mount package (3mm x 3mm). Applications are integrated automobile and marine GPS receivers.
