GPS/GNSS Low-Noise Amplifiers

General Description

Features

S High Power Gain: 17.8dB (MAX2687)

The MAX2687/MAX2689/MAX2694 low-noise amplifiers

(LNAs) are designed for GPS L1, Galileo, and GLONASS

applications. Designed in Maxim’s advanced SiGe pro-

cess, the devices achieve high gain and low noise figure

while maximizing the input-referred 1dB compression

point and the 3rd-order intercept point. The MAX2687/

MAX2689/MAX2694 provide high gains of 12dB, 15dB,

and 18dB, respectively. Each is optimized for high

linearity.

S Low Noise Figure: 0.85dB (MAX2687)

S Integrated 50Ω Output Matching Circuit

S Low Supply Current: 4.5mA (MAX2694)

S Wide Supply Voltage Range: 1.6V to 3.6V

S Low Bill of Materials: One Inductor, Two

Capacitors

S Small Footprint: 0.86mm x 0.86mm

The devices operate from a +1.6V to +3.6V 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).

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