CBP-1555C+

Overview

The CBP-1555C+ is an active ceramic resonator band pass filter manufactured by Mini-Circuits. It operates with a center frequency of 1.555 GHz and provides a bandwidth of 60 MHz, spanning from 1525 MHz to 1585 MHz. The component features a 50 Ohm impedance and exhibits an insertion loss of 2.5 dB. Packaged in a 13-SMD module format, it complies with RoHS and REACH standards.

Feature Summary

• Utilizes coaxial-ceramic resonator technology for stable RF filtering performance
• Designed as a surface mount device for compact PCB integration
• Provides defined passband characteristics within the specified frequency range

Applications

• RF front-end filtering in wireless communication systems
• Signal conditioning in radio frequency modules
• Frequency selection in microwave circuit designs

Procurement Notes

Verify the specific ordering suffix and package variant against the official Mini-Circuits datasheet before procurement. Confirm that the 13-SMD footprint matches your PCB layout requirements. Ensure compliance with RoHS and REACH directives is documented for your supply chain records. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a fixed center frequency of 1.555 GHz is required with a 60 MHz bandwidth. Consider the 2.5 dB insertion loss impact on system gain. Evaluate the 13-SMD package dimensions for spatial constraints. Verify compatibility with 50 Ohm system impedance to minimize reflection losses in the signal path.

Part Context

This component belongs to the Mini-Circuits CBP series of coaxial-ceramic resonator filters. These filters are engineered for applications requiring passbands from DC up to 6 GHz. The series offers fractional bandwidths ranging from less than 1% to 25%, providing versatile options for narrow to moderate bandwidth RF filtering needs.

Replacement Considerations

Consult the Mini-Circuits replacement guide for direct substitutes. Verify equivalent center frequency, bandwidth, and impedance specifications. Check for compatible package styles such as the 13-SMD module. Ensure electrical parameters like insertion loss meet or exceed original design requirements.
