The RF3931 is a 48V 30W high power discrete amplifier designed for commercial
wireless infrastructure, cellular and WiMAX infrastructure, industrial/scien-
tific/medical, and general purpose broadband amplifier applications. Using an
advanced high power density Gallium Nitride (GaN) semiconductor process, these
high-performance amplifiers achieve high efficiency and flat gain over a broad fre-
quency range in a single amplifier design. The RF3931 is an unmatched GaN tran-
sistor packaged in a hermetic, flanged ceramic package. This package provides
excellent thermal stability through the use of advanced heat sink and power dissi-
pation technologies. Ease of integration is accomplished through the incorporation
of simple, optimized matching networks external to the package that provide wide-
band gain and power performance in a single amplifier.
