MAX2679/MAX2679B
EVALUATION KIT AVAILABLE
GPS/GNSS Ultra-Low Current
Low-Noise Amplifier
General Description
The MAX2679 and MAX2679B low-noise amplifiers (LNA)
are designed for GPS L1, Galileo, and GLONASS
applications. The devices achieve high gain and low noise
figure while maximizing the input-referred 1dB compression
point and the 3rd-order intercept point. The MAX2679
achieves excellent performance while consuming only
1mA supply current and providing 0.95dB noise figure.
The MAX2679B achieves excellent performance while
consuming only 650µA and providing 1.03dB noise figure.
The MAX2679/MAX2679B operates from a +1.08V to
+1.98V single supply. The devices are available in a very
small, lead-free, RoHS-compliant, 0.83mm x 0.83mm
wafer-level package (WLP).

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

For the latest package outline information and land patterns (footprints), go to www.maximintegrated.com/packages. Note that a “+”,
“#”, or “-” in the package code indicates RoHS status only. Package drawings may show a different suffix character, but the drawing
pertains to the package regardless of RoHS status.
Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board.

Electrical Characteristics
(VCC = 1.08V to 1.98V, TA = -40°C to +85°C. Typical values are at VCC = 1.8V and TA = +25°C, unless otherwise noted. Limits are
100% tested at TA = +25°C. Limits over the operating temperature range and relevant supply voltage range are guaranteed by design
and characterization. Specifications marked "GBD" are guaranteed by design and not production tested.)
