Product Description
IF or RF Buffer Amplifiers
The RF3398 is a general purpose, low-cost RF amplifier IC. The device is manufac-
tured on an advanced Gallium Arsenide Heterojunction Bipolar Transistor (HBT) pro-
cess, and has been designed for use as an easily-cascadable 50Ω gain block.
Applications include IF and RF amplification in wireless voice and data communica-
tion products operating in frequency bands up to 6000MHz. The device is self-con-
tained with 50Ω input and output impedances and requires only two external DC-
biasing elements to operate as specified. The device is designed for cost effective
high reliability in a plastic package. The 3mmx3mm footprint is compatible with
standard ceramic and plastic Micro-X packages.
