The RF3928B is a 65V 380W high power discrete amplifier designed for S-Band
pulsed radar, Air Traffic Control and Surveillance, and general purpose broadband
amplifier applications. Using an advanced high power density Gallium Nitride (GaN)
semiconductor process, these high-performance amplifiers achieve high output
power, high efficiency and flat gain over a broad frequency range in a single pack-
age. The RF3928B is a matched 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 through the incorporation of simple, optimized matching networks
external to the package that provide wideband gain and power performance in a
single amplifier.
