RF5189
3V, 2.45GHz LINEAR POWER AMPLIFIER
The RF5189 is a linear, medium-power, high-efficiency amplifier IC designed specif-
ically for battery-powered WLAN applications such as PC cards, mini PCI, and com-
pact 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 trans-
mitters. 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.
