350W - 50V HF/VHF DMOS TRANSISTOR
Download Datasheet
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
