Procurement Notes

Verify the exact part number suffix against official Mini-Circuits documentation to ensure correct specification alignment. Confirm that the SMA connector type matches your system requirements. Check current availability status as lead times may vary. Ensure environmental ratings meet your operational temperature needs. Validate impedance matching for optimal signal integrity in your specific application design.

Selection Notes

Select this component when a narrow bandpass characteristic is required around 1260 MHz. Consider the 5.0 W power handling capability for high-signal environments. Evaluate the physical dimensions and inline mounting style against your enclosure constraints. Compare insertion loss and rejection specs against alternative filters to ensure adequate signal-to-noise ratio for your system architecture.

Part Context

This model belongs to the ZX75BP series of ceramic resonator bandpass filters from Mini-Circuits. These components are designed for applications demanding high stability and consistent performance across varying conditions. The series typically offers compact form factors suitable for modern RF designs. This specific variant targets the 1.2 GHz region, distinguishing it from other frequencies in the lineup.

Replacement Considerations

Consult Mini-Circuits official substitution guides for verified alternatives. Cross-reference center frequency and bandwidth tolerances carefully.
