Product Description

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 50鈩?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.
