1575MHz GPS Front-End Amplifier
General Description
The MAX12000 GPS front-end amplifier IC is designed
for marine GPS satellite navigation antenna modules or
for any application that needs to compensate for cable
losses from the GPS antenna to receiver. Two uncondi-
tionally 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.
The MAX12000 is designed to operate at the GPS fre-
quency of 1575MHz with a 34.8dB typical cascaded gain
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 pow-
er-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).

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
