Procurement Notes

Verify the exact datasheet version when sourcing this component, as specifications may be updated by the manufacturer. Confirm that the SMA connector interface matches your system requirements. Ensure the 50 Ohm impedance aligns with your circuit design. Check for compliance certifications such as RoHS and REACH if required for your deployment environment. Validate the power handling rating against your operational signal levels to ensure reliability.

Selection Notes

Select this component when a narrow-band passband centered at 778 MHz is required. The 10 MHz bandwidth suits applications needing precise frequency isolation. Consider the 100 Watt power handling if operating in high-power scenarios. The wide stopband up to 3300 MHz offers significant out-of-band rejection. Ensure compatibility with SMA interfaces and 50 Ohm system impedance before integration.

Part Context

This part belongs to Mini-Circuits' ZVBP series of coaxial cavity filters. These components are engineered for narrow-band applications requiring high selectivity and stability. The series typically employs resonant structures to achieve high Q-factors, making them suitable for specialized RF filtering tasks where standard LC filters may not provide sufficient performance or power handling capabilities.

Replacement Considerations

Consult Mini-Circuits official documentation for direct cross-references. Verify that any substitute maintains the 773-783 MHz passband, 50 Ohm impedance, and SMA interface. Ensure the replacement meets the 100 Watt power handling requirement and similar stopband characteristics up to 3300 MHz.
