RFHA3944

65W GaN Wide-Band Power Amplifier

The RFHA3944 is a 48V, 65W high power discrete amplifier

designed for military communications, electronic warfare, general

purpose broadband amplifier, commercial wireless infrastructure,

and industrial/scientific/medical applications. Using a second

generation advanced high power density gallium nitride (GaN)

semiconductor process with improved linearity, these high-

performance amplifiers achieve high efficiency, excellent linearity,

and flat gain and power over a broad frequency range in a single

amplifier design. The RFHA3944 is an unmatched GaN transistor,

packaged in a hermetic flanged ceramic package. This package

provides excellent thermal stability through the use of advanced

heat sink and power dissipation technologies. Ease of integration

is accomplished by incorporating simple, optimized matching

networks external to the package that provide wideband gain and

power performance in a single amplifier.
