Product Description
The RF3118 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
1850MHz to 1910MHz band. The RF3118 has a digital
control line for low power application to reduce the cur-
rent drain. The device is self-contained with 50鈩?input
and output that is matched to obtain optimum power, effi-
ciency, and linearity characteristics. The module is an
ultra-small 6mmx6mm land grid array with backside
ground.
