GPS/GNSS Ultra-Low-Noise-Figure LNAs
General Description
The MAX2667/MAX2669 high-gain, low-noise amplifiers
(LNAs) are designed for GPS L1, Galileo, and GLONASS
applications. Designed in Maxim’s advanced SiGe pro-
cess, the devices achieve a high gain and our lowest
noise figure, while maximizing the input-referred 1dB
compression point and the 3rd-order intercept point.
The devices operate from a +1.6V to +3.3V single sup-
ply. The MAX2667 is optimized for low current. The
MAX2669 is optimized for high linearity. The shutdown
feature in the device reduces the supply current to be
less than 10μA. The devices are available in a very small,
lead-free, RoHS-compliant, 0.86mm x 1.26mm x 0.65mm
wafer-level package (WLP).
