The device delivers an output power of 1 W, achieving a power gain of 14.6 ± 0.4 dB and an efficiency between 51% and 53%. It supports a load mismatch of 20:1 and features BeO-free amplifier construction.

Feature Summary

• Excellent thermal stability
• BeO-free amplifier construction

Applications

• UHF RFID readers
• Two-way radio communication systems

Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or official channels. Confirm the part status as NRND (Not Recommended for New Designs) before procurement. Ensure compatibility with existing RF circuit designs and thermal management requirements specific to UHF applications.

Selection Notes

Select this component for fixed-frequency UHF applications requiring 1 W output power. Consider the 7.2 V supply requirement and 14.6 dB gain characteristics. Evaluate thermal solutions due to the device's operational constraints in compact radio designs.

Part Context

The PD84001 serves as the core active element in evaluation boards like the STEVAL-TDR017V1. It is specifically engineered for high-efficiency amplification in the 860-960 MHz band, supporting robust performance in portable and fixed UHF communication infrastructure.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the component is marked NRND, alternative LDMOS transistors from other manufacturers or newer STMicroelectronics series should be evaluated for functional equivalence.
