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.
