Rainbow Electronics MAX2659 - Manual

General Description
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 +3.3V 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.
