Product Description
The RF2129 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 packaged in an 8-lead plastic package with a
backside ground and is self-contained with the exception
of the output matching network and power supply feed
line.
