RF5322

3V TO 4.5V, 2.4GHz TO 2.5GHz

LINEAR POWER AMPLIFIER

The RF5322 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 2.2mmx2.2mm, 8-pin, QFN with

a backside ground. The RF5322 is designed to maintain linearity over a wide range

of supply voltages and power outputs. The RF5322 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.
