Product Description
The RF5112 is a linear, medium-power, high-efficiency, two-stage amplifier IC
designed specifically for battery-powered WiFi 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 3mmx3mmx0.9mm, 16-pin,
QFN with a backside ground. The RF5112 is designed to maintain linearity over a
wide range of supply voltage and power output.
