Product Description
The RF5622 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 2mmx2mm, 8-pin, QFN with a backside 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 components internally
which reduces the component count used externally and makes it easier
to incorporate on any design.
