RF3223
0 HIGH LINEARITY/DRIVER AMPLIFIER
RoHS Compliant & Pb-Free Product
Typical Applications
• Basestation Applications
• GSM/EDGE Systems
• Cellular and PCS Systems
• CDMA, W-CDMA Systems
• Final PA for Low-Power Applications
Product Description
The RF3223 is a high-efficiency GaAs Heterojunction
Bipolar Transistor (HBT) amplifier packaged in a low-cost
surface-mount package. This amplifier is ideal for use in
applications requiring high-linearity and low noise figure
over the 500MHz to 3GHz frequency range. The RF3223
operates from a single 5V power supply, and is assem-
bled in an economical 3mmx3mm QFN package.
