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.
