The device is manufactured on an advanced In Ga P Gallium Arsenide Heterojunction Bipolar Transistor (HBT) process, and has been designed for use as the final RF amplifier in 2.5GHz OFDM and other spreadspectrum 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 ponents internally which reduces the ponent count used externally and makes it easier to incorporate on any design.
