Product Description
The RF5622 is a linear, medium-power, high-efficiency, two-stage ampli-
fier IC designed specifically for battery-powered WiFi applications such as
PC cards, mini PCI, and compact flash applications. The device is manu-
factured 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 2.2mmx2.2mmx0.45mm, 8-pin, QFN with a back-
side ground. The RF5622 is designed to maintain linearity over a wide
range of supply voltage and power output. The RF5622 also has built-in
power detector and incorporates the input and interstage matching com-
ponents internally which reduces the component count used externally
and makes it easier to incorporate on any design.
