MAX2691

L2 Band GPS Low-Noise Amplifier

General Description

Features

The MAX2691 low-noise amplifier (LNA) is designed for

GPS L2 applications. Designed in Maxim’s advanced

SiGe process, the device achieves high gain and

low noise figure while maximizing the input-referred 1dB

compression point and the 3rd-order intercept point. The

MAX2691 provides a high gain of 17.5dB and sub 1dB

noise figure.

S High-Power Gain: 17.5dB

S Low-Noise Figure: 0.93dB

S Integrated 50Ω Output Matching Circuit

S Low Supply Current: 4.3mA

S Wide Supply Voltage Range: 1.6V to 3.6V

S Low Bill of Materials: One Inductor, Two

The device operates from a +1.6V to +3.6V single sup-

ply. The optional shutdown feature in the device reduces

the typical supply current to 4FA. The device is available

in a very small, lead-free, RoHS-compliant, 0.86mm x

0.86mm x 0.65mm wafer-level package (WLP).

Capacitors

S Small Footprint: 0.86mm x 0.86mm

S Thin Profile: 0.65mm

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