Procurement Notes

Verify the exact part number suffix against official documentation, as variations such as HR3 or HSR3 indicate specific packaging configurations like tape and reel quantities. Confirm RoHS compliance status and current lifecycle stage through authorized distributors or manufacturer channels before procurement.

Selection Notes

Select this component for designs requiring high linearity and efficiency in the 865-960 MHz band. Ensure thermal management accommodates junction temperatures up to 225°C and case temperatures up to 150°C. Verify bias conditions align with typical Class AB or C operation requirements for optimal gain and efficiency.

Part Context

This RF power transistor belongs to the LDMOS family from Freescale Semiconductor, now NXP USA Inc. It is engineered specifically for wireless communication infrastructure, providing robust performance in demanding cellular network environments while maintaining reliability under continuous wave and modulated signal conditions.

Replacement Considerations

Consult official substitution guides for equivalent devices within the same frequency range and power class. Verify pinout compatibility and thermal characteristics when considering alternatives.
