  • 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
