GPS/GNSS Low-Noise Amplifiers
General Description
The MAX2686/MAX2688 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 ultra-low-noise figure
while maximizing the input-referred 1dB compression
point and the 3rd-order intercept point. The MAX2686
provides a high gain of 19dB. The MAX2688 supplies
15dB of gain while attaining higher linearity.
The devices operate from a +1.6V to +3.3V single sup-
ply. The optional shutdown feature in the devices reduc-
es the supply current to less than 10FA. The devices
are available in a very small, lead-free, RoHS-compliant,
0.86mm x 0.86mm x 0.65mm wafer-level package (WLP).
