Procurement Notes

Verify the manufacturer designation as Freescale Semiconductor or NXP Semiconductors, as corporate acquisitions may affect labeling. Confirm the specific suffix 'MBR1' corresponds to the required tape-and-reel packaging format. Ensure the component meets current RoHS compliance standards before integration into final assemblies.

Selection Notes

Select this component when designing amplifiers requiring wide bandwidth coverage from 470 to 860 MHz. Evaluate thermal resistance requirements carefully due to the high power density inherent in LDMOS structures. Consider the 50V operating voltage constraint when designing bias networks and matching circuits for optimal linearity and efficiency.
