• Optimized for common source push-pull configuration in large signal applications
• Designed for 100 V DC operation in HF/VHF/UHF frequency bands

Applications

• RF power amplification in broadcast transmitters
• Industrial heating and plasma generation systems
• Military communication equipment requiring high linearity

Procurement Notes

Verify the specific suffix 'F' against official STMicroelectronics documentation to confirm pinout and electrical tolerances, as variations exist within the STAC3932 family. Confirm RoHS compliance status and check for active production status or last-time buy notices through authorized distributors. Ensure the supplier provides valid traceability documents for aerospace or automotive qualification if required by the application standard.

Selection Notes

Select the STAC3932F when designing circuits requiring 580 W output power at frequencies around 123 MHz. Ensure the PCB layout supports the STAC-244B package thermal requirements and matches the impedance network for the specified 24.6 dB gain. Compare against the STAC3932B variant if higher voltage ratings are needed, noting that the B version may differ in specific breakdown characteristics despite similar power handling.

Part Context

This component belongs to the STAC3932 series of RF power MOSFETs from STMicroelectronics. The series is characterized by silicon technology optimized for high efficiency and linearity in radio frequency applications. The STAC3932F shares core performance metrics with other variants in the family but may have distinct packaging or testing specifications defined by the manufacturer's datasheet.

Replacement Considerations

Publicly confirmed substitute part numbers for the STAC3932F are not available in the provided reference data. Engineers should consult STMicroelectronics directly for qualified alternatives or cross-reference with the STAC3932B if electrical parameters align with the design requirements.
