Procurement Notes
Verify the specific part number against official Mini-Circuits documentation to ensure compatibility with system requirements. Confirm that the SMA connector type and 50 Ohm impedance match the design specifications. Check for RoHS compliance status if required by project regulations. Ensure handling procedures protect the ceramic resonator from mechanical stress during installation.
Selection Notes
Select this component when a fixed center frequency of 1.28 GHz is required with a 240 MHz bandwidth. The 2 dB insertion loss specification should be evaluated against system link budget constraints. The SMA connector style dictates the physical integration method within the RF chain. Consider the operating temperature range limits for environmental suitability.
Part Context
This model belongs to the ZX75BP series of coaxial-ceramic resonator filters produced by Mini-Circuits. The series is characterized by high stability and compact form factors suitable for various RF applications. The product line focuses on providing reliable signal filtering solutions with consistent electrical performance across the specified frequency bands.
Replacement Considerations
Consult Mini-Circuits official documentation for verified substitute part numbers. Cross-referencing requires matching center frequency, bandwidth, impedance, and connector type. Generic replacements may not maintain identical electrical characteristics or physical dimensions.
