Product Description
The RF5176 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 3V
CDMA-2000 and W-CDMA handsets as well as other
applications in the 1850MHz to 2000MHz band. The
device is self-contained, and the output can be easily
matched to obtain optimum power, efficiency, and linear-
ity characteristics over all recommended supply voltages.
The device has a continuously variable bias circuit to
allow idle current to be optimized for a given output
power.
