Product Description

The RF2146 is a high-power, high-efficiency linear ampli-

fier IC. The device is manufactured on an advanced Gal-

lium Arsenide Heterojunction Bipolar Transistor (HBT)

process, and has been designed for use as the final RF

amplifier in 4-cell CDMA handheld digital cellular equip-

ment, spread-spectrum systems, and other applications

in the 1500MHz to 2000MHz band. The device is self-

contained with 50鈩?input and the output can be easily

matched to obtain optimum power, efficiency, and linear-

ity characteristics.
