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.

Note 1: All specification and characterization data has been gathered on standard FR-4 evaluation boards. These evaluation boards are
not optimized for frequencies above 2.5GHz. Performance above 2.5GHz may improve if a high performance PCB is used.
Note 2: The RF3398 must be operated at or below 60mA in order to achieve the thermal performance listed above. While the RF3398
may be operated at higher bias currents, 40mA is the recommended bias to ensure the highest possible reliability and electrical
performance.
Note 3: Because of process variations from part to part, the current resulting from a fixed bias voltage will vary. As a result, caution
should be used in designing fixed voltage bias circuits to ensure the worst case bias current does not exceed 60mA over all
intended operating conditions.
