VHF power MOS transistor

Silicon N-channel enhancement mode vertical D-MOS transistor designed for large signal amplifier applications in the VHF frequency range. The transistor is encapsulated in a 4-lead SOT123A flange package, with a ceramic cap. All leads are isolated from the flange. Matched gate-source voltage (VGS) groups are available on request.

Features and benefits

  • High power gain
  • Low noise figure
  • Easy power control
  • Good thermal stability
  • Withstands full load mismatch

Applications

  • Large signal amplifier applications in the VHF frequency range
