Product Description

The RF2189 is a linear, medium-power, high-efficiency

amplifier IC designed specifically for low voltage opera-

tion. The device is manufactured on an advanced Gallium

Arsenide Heterojunction Bipolar Transistor (HBT) pro-

cess, and has been designed for use as the final RF

amplifier in 2.5GHz spread-spectrum transmitters. The

device is provided in a 16-pin leadless chip carrier with a

backside ground and is self-contained with the exception

of the output matching network and power supply feed

line.
