RF3398
0 GENERAL PURPOSE AMPLIFIER
RoHS Compliant & Pb-Free Product
Typical Applications
• Basestation Applications
• Driver Stage for Power Amplifiers
• Broadband, Low-Noise Gain Blocks
• IF or RF Buffer Amplifiers
• Final PA for Low-Power Applications
• High Reliability Applications
Product Description
The RF3398 is a general purpose, low-cost RF amplifier
IC. The device is manufactured on an advanced Gallium
Arsenide Heterojunction Bipolar Transistor (HBT) pro-
cess, and has been designed for use as an easily-cas-
cadable 50Ω gain block. Applications include IF and RF
amplification in wireless voice and data communication
products operating in frequency bands up to 6000MHz.
The device is self-contained 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.
