RF Power Dividers/Splitters Procurement Notes

Verify the specific datasheet version and revision level prior to procurement, as documentation may indicate advanced development status or performance variations based on testing conditions. Confirm that the SMA connector type matches system requirements. Ensure environmental ratings align with deployment conditions. Cross-reference part numbers carefully, as similar models exist within the product family with different frequency ranges or port configurations.

RF Power Dividers/Splitters Selection Notes

Select this component when a three-way split is required across the 1 to 300 MHz spectrum. Consider the 30 dB isolation specification for interference-sensitive environments. Evaluate the physical footprint against available space constraints due to its specific dimensional profile. Compare against other MACOM dividers like the DS-328 if higher frequency coverage up to 700 MHz is needed instead.
