The RF3100-2 is a high-power, high-efficiency linear amplifier module targeting 3V hand-held systems. The device is manufactured on an advanced Gallium Arsenide Heterojunction Bipolar Transistor (HBT) process, and has been designed for use as the final RF amplifier in dualmode 3V CDMA/AMPS hand-held digital cellular equipment, spread-spectrum systems, and other applications in the 824MHz to 849MHz band. The RF3100-2 has a digital control line for low power application to reduce the current drain. The device is self-contained with 50 input and output that is matched to obtain optimum power, efficiency, and linearity characteristics. The module is an ultra-small 6mmx6mm land grid array with backside ground.
