UHF power LDMOS transistor

Silicon N-channel enhancement mode lateral D-MOS transistor encapsulated in a 2-lead flange package (SOT467C) with a ceramic cap. The common source is connected to the mounting flange.

Features and benefits

  • High power gain
  • Easy power control
  • Excellent ruggedness
  • Source on underside eliminates DC isolators, reducing common mode inductance
  • Designed for broadband operation (HF to 1 GHz)

Applications

  • Communication transmitter applications in the UHF frequency range
