General Description  
Features  
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.

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).
