STAC2942FW

Overview

The STAC2942FW is an N-channel RF MOSFET transistor manufactured by STMicroelectronics, designed for large-signal applications up to 250 MHz. It features gold metallization and operates with a 50 V DC supply. The device delivers a minimum output power of 350 W with a gain of 21 dB at 175 MHz. It utilizes the ST air-cavity STAC packaging technology for excellent thermal stability and supports common source push-pull configurations.

Feature Summary

• Gold metallization for enhanced performance
• Excellent thermal stability
• Common source push-pull configuration support

Applications

• HF/VHF/UHF RF power amplification
• Large signal applications up to 250 MHz

Procurement Notes

Verify the specific suffix 'FW' against official STMicroelectronics documentation to confirm exact package or tape-and-reel specifications. Ensure compatibility with existing board layouts and thermal management systems before procurement.

Selection Notes

Select this component for high-power RF designs requiring 350 W output at 50 V. Consider the 21 dB gain at 175 MHz when designing amplifier stages. Verify that the system can accommodate the STAC package form factor and associated mounting requirements.

Part Context

This part belongs to the STAC2942 family of HF/VHF/UHF RF power N-channel MOSFETs from STMicroelectronics. It shares core electrical characteristics with variants like the STAC2942B but may differ in packaging or handling specifications as indicated by the suffix.

Replacement Considerations

The STAC2942B is a confirmed substitute within the same product family. Verify pinout and package dimensions match the design constraints before substitution.
