• 3V CDMA Cellular Handsets
RF2175
3V 400MHz LINEAR AMPLIFIER
• Portable Battery-Powered Equipment
Product Description
The RF2175 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 TETRA hand-
held digital cellular equipment, spread-spectrum systems,
and other applications in the 380MHz to 512MHz band.
The RF2175 has an analog bias control voltage to maxi-
mize efficiency. The device is self-contained with 50Ω
input, and the output can be easily matched to obtain
optimum power, efficiency, and linearity characteristics.
The package is a small SSOP-16 plastic with backside
ground.
