RFHA3942
35W GaN Wide-Band Power Amplifier
RFHA3942
The RFHA3942 is a 48V, 35W 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 RFHA3942 is an unmatched GaN transistor,
packaged in a 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.
