CBP-770C+

Overview

The CBP-770C+ is a ceramic-coaxial-resonator based bandpass filter in a shielded package fabricated using SMT technology. It offers a center frequency of 770 MHz with a 20 MHz bandwidth (760 to 780 MHz). The component features an insertion loss of 1 to 2 dB and operates at a 50 Ohm impedance.

Feature Summary

• Ceramic-coaxial-resonator construction for stable performance
• Shielded surface-mount technology (SMT) package
• Narrow bandwidth design with excellent rejection characteristics

Applications

• RF signal processing systems requiring precise frequency selection
• Communication equipment operating within the 760-780 MHz range
• Test and measurement instrumentation filters

Procurement Notes

Verify the specific datasheet revision and RoHS/REACH compliance status directly from Mini-Circuits official documentation before integration. Confirm that the shielded SMT package dimensions align with your PCB layout constraints. Ensure thermal management strategies account for the specified power handling capabilities during operation.

Selection Notes

Select this component when a narrow 20 MHz bandwidth centered at 770 MHz is required. The 50 Ohm impedance matches standard RF transmission lines. Consider the low profile design for space-constrained applications. Verify that the 1-2 dB insertion loss meets system sensitivity requirements.

Part Context

This part belongs to the Mini-Circuits CBP series of 50Ω coaxial-ceramic resonator filters. These filters typically offer passbands from DC up to 6GHz with fractional bandwidths ranging from less than 1% to 25%. The series utilizes low-profile designs suitable for modern electronic assemblies.

Replacement Considerations

Consult Mini-Circuits official substitution guides for verified equivalents. Do not assume functional compatibility with generic bandpass filters due to specific resonator tuning and rejection specifications unique to this model.
