Product Description

The RF3105 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/AMPS handheld digital cellular equipment,

spread-spectrum systems, and other applications in the

824MHz to 849MHz band. The RF3105 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.
