UHF power LDMOS transistor

Silicon N-channel enhancement mode lateral D-MOS push-pull transistor in a SOT540A package with ceramic cap. The common source is connected to the mounting flange.

Features and benefits

  • High power gain
  • Easy power control
  • Excellent ruggedness
  • Designed to withstand abrupt load mismatch errors
  • Source on underside eliminates DC isolators; reducing common mode inductance
  • Designed for broadband operation (UHF band)
  • Internal input and output matching

Applications

  • Communication transmitter applications in the UHF frequency range
