Product Description
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 dual-
mode 3V CDMA/AMPS hand-held digital cellular equip-
ment, 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.
