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 50Ω input and the output can be easily
matched to obtain optimum power, efficiency, and linear-
ity characteristics.
