350W - 50V HF/VHF DMOS TRANSISTOR

The SD2943 is a gold metallized N-channel MOS field-effect RF power transistor. It is used for 50 V DC large signal applications up to 150 MHz. The SD2943 offers a 20% higher power saturation than the SD2933, and is ideal for ISM applications where reliability and ruggedness are critical factors.

Key Features

  • High power capability
  • POUT = 350 W min. with 22 dB gain@30 MHz
  • PSAT = 450 W
  • Low RDS(on)
  • Thermally enhanced packing for lower junction temperatures
  • Gold metallization
  • Excellent thermal stability
  • Common source configuration
