GPS/GNSS Low-Noise Amplifiers
with Integrated LDO
General Description
The MAX2686L /MAX2693L low-noise amplifiers (LNAs)
are designed for GPS L1, Galileo, and GLONASS applica-
tions. Designed in Maxim’s advanced SiGe process, the
devices achieve high gain and low noise figure while maxi-
mizing the input-referred 1dB compression point and the
3rd-order intercept point. Both devices include an internal
LDO ideal for battery-powered applications. For current-
sensitive applications, the MAX2693L achieves excellent
performance while consuming only 1.8mA current.
The devices operate from a +1.6V to +4.2V single supply.
The optional shutdown feature in the devices reduces the
supply current to less than 20FA. The devices are avail-
able in a very small, lead-free, RoHS-compliant, 0.86mm x
0.86mm x 0.65mm wafer-level package (WLP).
