Sanland’s AL411 is a flat gain, high linearity, ultra-low noise amplifier in a micro 2.0 x 2.0 x 0.75mm3 8-pin DFN package. The LNA provides a gain flatness of 2dB (peak to peak) over a wide bandwidth from 2 to 4.2 GHz. 

The 0.25um GaAs enhanced PHEMT technology is used to realize the low noise amplifier with low noise and high-linearity. It is packaged in a green / RoHS- compliant 2x2 mm industry standard package.

The internal active bias circuit provides stable temperature and process change performance. The LNA provides the ability to adjust the power current externally . The power supply voltage is applied to RFOUT/VDD pin through the inductance of RF choke.
