Preliminary

RF2175

3V 400MHZ LINEAR AMPLIFIER

Typical Applications

• 3V TETRA Cellular Handsets

• 3V CDMA Cellular Handsets

• 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 maximize efficiency. The device is self-con-

tained with 50Ω input, and the output can be easily

matched to obtain optimum power, efficiency, and linear-

ity characteristics. The package is a small SSOP-16 plas-

tic with backside ground.
