3V, 2.45GHz LINEAR POWER AMPLIFIER
RoHS Compliant & Pb-Free Product
Typical Applications
• IEEE802.11B WLAN Applications
• 2.5GHz ISM Band Applications
• Wireless LAN Systems
• Commercial and Consumer Systems
• Portable Battery-Powered Equipment
• Spread-Spectrum and MMDS Systems
Product Description
The RF5189 is a linear, medium-power, high-efficiency
amplifier IC designed specifically for battery-powered
WLAN 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 WLAN 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 integrat-
ing all matching circuitry onto the chip.
