Procurement Notes

Verify the specific datasheet revision and electrical parameter tolerances against your design requirements before procurement. Confirm that the 16-SMD package dimensions align with your PCB footprint constraints. Ensure compatibility with standard surface-mount reflow soldering profiles. Check for any specific handling instructions regarding the ceramic resonator structure.

Selection Notes

Select this component when a fixed center frequency of 2250 MHz with a 500 MHz bandwidth is required. The coaxial-ceramic design suits applications needing robust performance without external tuning. Consider the physical size of the 16-SMD module relative to available board space. Evaluate if the inherent Q-factor meets the selectivity needs of your specific signal path.

Part Context

This part belongs to the CBP series of coaxial-ceramic resonator filters from Mini-Circuits. These components are engineered for operation from DC up to 6GHz. The series emphasizes low profile designs and fractional bandwidths ranging from less than 1% to 25%. The CBP-2250A+ represents a specific configuration within this broader family of RF filtering solutions.

Replacement Considerations
