Overview
The SD2942W is a gold metallized N-channel MOS field-effect RF power transistor produced by STMicroelectronics. This transistor is designed for high-power applications in the HF/VHF/UHF frequency range, offering 25% lower RDS(ON) compared to industry standards and 20% higher power saturation than the ST SD2932. These characteristics make the SD2942W ideal for 50 V DC very high power applications up to 250 MHz.
