Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging configuration. The R1 suffix indicates a standard tape and reel quantity of 500 units on a 44 mm, 13-inch reel. Ensure procurement channels provide original manufacturer documentation to validate component authenticity and traceability prior to integration into production systems.

Selection Notes

Select this component for designs requiring high power density within a broad frequency spectrum without complex impedance matching networks. Evaluate thermal management requirements carefully, as continuous use at maximum junction temperatures affects mean time to failure. Confirm that system biasing supports the specified quiescent current and gate threshold voltages for optimal performance.

Part Context

This part belongs to the Freescale Semiconductor RF Power Field Effect Transistors family, specifically categorized as Lateral N-Channel Enhancement-Mode MOSFETs. It serves as a high-performance solution for radio frequency power amplification, bridging the gap between driver stages and final output stages in broadband communication and industrial transmission systems.

Replacement Considerations

Consult official replacement lists for verified substitutes. Cross-referencing requires matching electrical parameters such as breakdown voltage, power handling, and frequency range.
