Product Description
The RF3934 is a 48V 120W 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 RF3934 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.

Caution! ESD sensitive device.
Exceeding any one or a combination of the Absolute Maximum Rating conditions may
cause permanent damage to the device. Extended application of Absolute Maximum
Rating conditions to the device may reduce device reliability. Specified typical perfor-
mance or functional operation of the device under Absolute Maximum Rating condi-
tions is not implied.
