UHF push-pull power MOS transistor

Silicon N-channel enhancement mode vertical D-MOS push-pull transistor designed for communications transmitter applications in the UHF frequency range. The transistor is encapsulated in a 4-lead, SOT268A balanced flange package, with two ceramic caps. The mounting flange provides the common source connection for the transistors.

Features and benefits

  • High power gain
  • Easy power control
  • Gold metallization ensures excellent reliability
  • Good thermal stability
  • Designed for broadband operation

Applications

  • UHF range
  • Vertical D-MOS transistor designed for communications transmitter applications
