RF3928B 380W GaN Wideband Pulsed Power Amplifier

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.

Features

  • Wideband Operation 2.8GHz to 3.4GHz
  • Advanced GaN HEMT and Heat-Sink Technologies
  • Optimized Evaluation Board Layout for 50Ω Operation
  • Integrated Matching Components for High Terminal Impedances
  • 65V Operation Typical Performance:
    • Pulsed Output Power 380W
    • Small Signal Gain 13dB
    • Drain Efficiency 50%
    • -40°C to 85°C Operating Temperature

Applications

  • Radar
  • Air Traffic Control and Surveillance
  • General Purpose Broadband Amplifiers
