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 RF5222 is designed to maintain linearity over a wide range of supply voltage and power output. The RF5222 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.
