Avionics LDMOS transistor

Silicon N-channel enhancement mode lateral D-MOS transistor encapsulated in a 2-lead SOT502A flange package 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 mounting base eliminates DC isolators, reducing inductance.

Applications

  • Avionics transmitter applications in the 960 MHz to 1215 MHz frequency range
  • Mode-S, TCAS and JTIDS, DME or TACAN
