Greetings: There is so much good stuff on RF Cafe that there is no way to list or
link to all of it here. Please use the Search box or the Site

RFMD’s new 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. The RF3928B is a matched GaN
transistor in a hermetic, flanged ceramic package. This package provides 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.
Wideband Operation 2.8 GHz to 3.4 GHz
Advanced GaN HEMT and Heat-Sink Technologies
Optimized Evaluation Board Layout for 50 Ω Operation
Integrated Matching Components for High Terminal Impedances
