The MAX2659 high-gain, low-noise amplifier (LNA) is

designed for GPS, Galileo, and GLONASS applications.

Designed in Maxim’s advanced SiGe process, the

device achieves a 20.5dB gain and an ultra-low-noise

figure of 0.8dB while maximizing the input-referred 1dB

compression point and the 3rd-order intercept point at

-12dBm and -5dBm, respectively.

The MAX2659 operates from a +1.6V to +3.6V single

supply and consumes only 4.1mA. The shutdown fea-

ture in the device reduces the supply current to be less

than 1µA. The MAX2659 is available in a very small,

lead-free, RoHS-compliant, 1.5mm x 1.0mm x 0.75mm,

6-pin µDFN package.

19-0797; Rev 3; 1/11
