Product Description
The RF5122 is a linear, medium-power, high-efficiency, two-stage amplifier IC
designed specifically for battery-powered WLAN applications such as PC cards, mini
PCI, and compact flash applications. The device is manufactured 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 RF5122 is designed to maintain linearity over a wide range
of supply voltages and power outputs. The RF5122 also has built-in power detector
and incorporates the input, interstage, and output matching components internally
which reduces the component count used externally and makes it easier to incorpo-
rate on any design.
