GPS/GNSS Front-End Amplifier
General Description
The MAX2670 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 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
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 perfor-
mance of the GPS/GNSS receiver. Additionally, a 3.4dB
gain step is provided to compensate for cable loss varia-
tion between different applications.
The device is designed to operate across all GNSS fre-
quency standards with a 34.8dB typical cascaded gain
and a 25mA supply current. The two LNA stages allow
the use of a wide range of GNSS filter types for maxi-
mum flexibility in system design. The final RF output pin,
which drives the cable to the GNSS 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.
This GPS/GNSS 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).
