CBP-1260C+

Overview

The CBP-1260C+ is a ceramic-coaxial-resonator bandpass filter from Mini-Circuits, housed in a shielded surface-mount technology (SMT) package. It operates with a center frequency of 1.26 GHz and provides a bandwidth of 120 MHz. The component features an insertion loss of 2 dB and is designed for 50 Ohm systems. This filter utilizes a low-profile design suitable for compact RF applications requiring high performance.

Feature Summary

• Utilizes ceramic-coaxial resonators for stable filtering characteristics
• Shielded SMT package construction minimizes external interference
• Low profile physical design facilitates dense PCB integration

Applications

• Wireless communication systems
• RF signal processing circuits
• Test and measurement equipment

Procurement Notes

Verify the specific datasheet version for the CBP-1260C+ to confirm exact electrical tolerances and mechanical dimensions prior to implementation. Ensure compatibility with standard SMT reflow profiles during assembly. Cross-reference the part number with official Mini-Circuits documentation to validate availability and manufacturing status before finalizing procurement plans.

Selection Notes

Select this component when a narrowband filter centered at 1.26 GHz is required within a constrained board area. The 120 MHz bandwidth suits applications needing moderate selectivity. Consider the 2 dB insertion loss impact on system gain budgets. The shielded SMT form factor is advantageous for reducing parasitic coupling in high-density layouts compared to through-hole alternatives.

Part Context

This part belongs to the Mini-Circuits CBP series, which offers coaxial-ceramic resonator filters with passbands ranging from DC to 6 GHz. These components are engineered for fractional bandwidths between less than 1% and 25%. The series emphasizes low-profile designs suitable for modern electronic devices requiring reliable RF filtering solutions.

Replacement Considerations

Consult the Mini-Circuits official documentation for verified substitute part numbers. Do not assume functional equivalence with other bandpass filters without confirming matching center frequencies, bandwidths, and impedance specifications.
