Qorvo's RF5189 is a linear, medium-power, high-efficiency amplifier IC designed specifically for battery-powered Wi-Fi applications such as PC cards, mini PCI, and compact flash applications. The device is designed for use as the final RF amplifier in 2.5GHz Wi-Fi and other spread-spectrum transmitters. The device is provided in a 12-pin QFN package with a backside ground. The RF5189 is designed to maintain linearity over a wide range of supply voltage and power output. The RF5189 is designed to reduce end-product BOM count by integrating all matching circuitry onto the chip.
