Product Description
The RF5189 is a linear, medium-power, high-efficiency 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 Gallium Arsenide Heterojunction Bipolar Transistor (HBT) process, and has been designed for use as the final RF amplifier in 2.5GHz WiFi 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.
