Product Description
The RF3100-3 is a high-power, high-efficiency linear
amplifier IC targeting 3V hand-held systems. The device
is manufactured on an advanced Gallium Arsenide Het-
erojunction 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 RF3100-3 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.
