The RF2152 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
800MHz to 950MHz band. The device is self-contained
with 50Ω input and the output can be easily matched to
obtain optimum power, efficiency, and linearity character-
istics. The package is a PSSOP-16 with backside ground.
