19-5518; Rev 0; 9/10

GPS/GNSS Ultra-Low-Noise-Figure LNAs

General Description

Features

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.

S 19dB High-Power Gain (MAX2667)

S Ultra-Low Noise Figure: 0.65dB

S Integrated 50Ω Output Matching Circuit

S Low 4.1mA Supply Current (MAX2667)

S Wide 1.6V to 3.3V Supply Voltage Range

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).

S Low Bill of Materials: Two Inductors, Three

Capacitors, and One Resistor

S Small Footprint: 0.86mm x 1.26mm

S Thin Profile: 0.65mm

S 0.4mm-Pitch Wafer-Level Package (WLP)
