• 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.
