Product Description
The RF3117 is a high-power, high-efficiency linear ampli-
fier module 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/AMPS handheld digital cellular equipment,
spread-spectrum systems, and other applications in the
824MHz to 849MHz band. The RF3117 has a digital con-
trol line for low power application to reduce the current
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.
