RF3833

25W GaN Wide-Band Power Amplifier

30MHz to 2000MHz

The RF3833 is a wideband Power Amplifier designed for CW and pulsed

applications such as wireless infrastructure, RADAR, two way radios, and

general purpose amplification. Using an advanced high power density

Gallium Nitride (GaN) semiconductor process, these high-performance

amplifiers achieve high efficiency, flat gain, and large instantaneous

bandwidth in a single amplifier design. The RF3833 is an input matched

GaN transistor packaged in an air cavity copper package which provides

excellent thermal stability through the use of advanced heat-sink and

power dissipation technologies. Ease of integration is accomplished

through the incorporation of optimized input matching network within the

package that provides wideband gain and power performance in a single

amplifier. An external output match offers the flexibility of further

optimizing power and efficiency for any sub-band within the overall

bandwidth.
