Product Description
The RF5263 is a linear power amplifier IC designed specifically for
medium power applications. The device is manufactured on an advanced
InGaP Heterojunction Bipolar Transistor (HBT) process, and has been
designed for use as the final RF amplifier in 802.11g/n access point
transmitters. The device is provided in a 4mmx4mm, 16-pin, leadless
chip carrier with a backside ground. The RF5263 is designed to maintain
linearity over a wide range of supply voltages and power outputs.
