RFHA1003

30MHz TO 512MHz, 9W GaN WIDEBAND

POWER AMPLIFIER

The RFHA1003 is a wideband Power Amplifier designed for CW and pulsed applica-

tions such as wireless infrastructure, RADAR, two way radios and general purpose

amplification. Using an advanced high power density Gallium Nitride (GaN) semi-

conductor process, these high-performance amplifiers achieve high efficiency, flat

gain, and large instantaneous bandwidth in a single amplifier design. The

RFHA1003 is an input matched GaN transistor packaged in an air cavity ceramic

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 exter-

nal output match offers the flexibility of further optimizing power and efficiency for

any sub-band within the overall bandwidth.
