Product Description
The RF5222 is a linear, medium-power, high-efficiency, two-stage ampli-
fier IC designed specifically for battery-powered WLAN applications such
as PC cards, mini PCI, and compact flash applications. The device is man-
ufactured on an advanced InGaP Gallium Arsenide Heterojunction Bipolar
Transistor (HBT) process, and has been designed for use as the final RF
amplifier in 2.5GHz OFDM and other spread-spectrum transmitters. The
device is provided in a 2.2mmx2.2mm, 8-pin, QFN with a backside
ground. The RF5222 is designed to maintain linearity over a wide range of
supply voltage and power output. The RF5222 also has built-in power
detector and incorporates the input and interstage matching components
internally which reduces the component count used externally and makes
it easier to incorporate on any design.
