SD2943 - HF/VHF/UHF RF power N-channel MOSFET

General Description

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 Order code SD2943W.
