MAX2678

GPS/GNSS Front-End Ampliﬁer

General Description

Features

● First Amplifier Noise Figure: 0.9dB

The MAX2678 GPS/GNSS front-end amplifier IC is

designed for automotive and marine GPS/GNSS satellite

navigation antenna modules, or for any application that

needs to compensate for cable losses from the antenna

to receiver. Two unconditionally stable low-noise amplifier

stages provide the high gain and integrated I/O matching

to minimize the need for external matching components

and eliminate the need for additional gain stages. The

IC features the option to place a bandpass ceramic or

surface acoustic wave (SAW) filter between the two amplifi-

er stages for improved immunity to out-of-band interferers.

Additionally, a 3.4dB-gain step is provided to compensate

for cable loss variation between different applications.

● High Gain:* 35dB

● 3.4dB Gain Step

● Shared V

and RFOUT2 Pin

● Integrated 50Ω Output Matching

● AMP 2 includes 50Ω Input Matching

● 3.0V to 5.25V Supply Voltage Range

● Small (3mm x 3mm) Low-Cost Package

● AEC-Q100 Qualified

● ESD Protected to ±2kV Human Body Model

● -40°C to +105°C Ambient Temperature Range

The device is designed to operate across all GNSS

frequency standards with a 35dB typical cascaded gain

and a 25mA supply current. The two LNA stages allow

the use of a wide range of GNSS filter types for maximum

flexibility in system design. The final RF output pin, which

drives the cable to the GNSS receiver, is also the power-

supply connection that accepts a DC supply in the 3.0V to

5.25V range. Alternatively, the DC supply can be applied

to pin 4.

Applications

● Integrated Automotive and Marine GPS Receivers

● Active Antennas

*First amplifier input is impedance matched (S = -10dB).

Second amplifier is set to high gain. Amplifiers are cascaded

without interstage filter.

This GPS/GNSS front-end amplifier is available in a lead-

free, 10-pin TDFN surface-mount package (3mm x 3mm).

Electrical performance is guaranteed over the extended

-40°C to +105°C temperature range.

Ordering Information and Typical Operating Circuit appear at end of data

sheet.
