Product Description
The RF3120 is a high-power, high-efficiency linear ampli-
fier IC targeting 3V handheld systems. The device is
manufactured on an advanced Gallium Arsenide Hetero-
junction Bipolar Transistor (HBT) process, and has been
designed for use as the final RF amplifier in dual-mode
3V CDMA hand-held digital cellular equipment, spread-
spectrum systems, and other applications in the
1750MHz to 1780MHz band. The RF3120 has a digital
bias control voltage for low current in standby mode. The
device is self-contained with 50鈩?input and output that is
matched to obtain optimum power, efficiency, and linear-
ity characteristics. The module is an ultra-small
6mmx6mm land grid array with backside ground.
