Product Description
The RF3857 is a dual channel switchable low noise amplifier with a very
high dynamic range designed for digital cellular, WiMAX, and WiFi applica-
tions. The device functions as an outstanding front end low noise ampli-
fier. The bias current may be set externally. The RF3857 combines two
receive paths, which is ideal in an application that requires two receive
paths, such as 1x2 and 2x2 MIMO for both WiFi and WiMax aplications.
The IC is featured in a standard QFN, 16-pin, 3mmx3mm plastic package.
