MAX2674/MAX2676

GPS/GNSS LNAs with Antenna Switch and Bias

General Description

Features

S Eliminate Discrete Antenna Sensing, Switching,

and Bias Networks

The MAX2674/MAX2676 are ultra-small, high-IP3, low-

noise amplifiers (LNAs) designed for GPS L1, Galileo,

and GLONASS applications. Designed in Maxim’s

advanced SiGe process, the devices are also equipped

with an autosensing feature for applications that enable

the use of external antennas. These high-performance

LNAs provide high gain and an ultra-low noise figure

while optimizing the input-referred 2dB compression

point and 3rd-order intercept point.

Autodetect Antenna Connection

Provide Antenna Bias

Short-Circuit Protection

S Wide 1.6V to 3.6V Supply Voltage Range

S Ultra-Small Footprint (0.86mm x 1.26mm) WLP

Package

S For Applications Without Antenna Port, Use Pin-

Compatible 4-Bump MAX2686/MAX2687/MAX2688

LNA

The ultra-small size is ideal for front-end modules and

receiver applications in cellular phones, smartphones,

PDAs, PNDs, or other custom GNSS applications. The

MAX2674/MAX2676 operate from a 1.6V to 3.6V single

supply. The MAX2674 is optimized for high gain, while

the MAX2676 is optimized for high linearity. A shutdown

feature is present in both devices reducing the supply

current to less than 10FA. The antenna port automati-

cally senses when an external antenna is connected,

eliminating the need for additional control circuitry

while also providing improved short-circuit protection.

The MAX2674/MAX2676 are available in an ultra-small,

RoHS-compliant 0.86mm x 1.26mm x 0.64mm wafer-

level package (WLP).

Applications

Front-End SAW Modules

Receiver Modules

Cellular and Smartphones

Telematics (Asset Tracking and Management)

Personal Navigation Devices (PNDs)

Recreational, Marine Navigation
