CBP3-2700BR+

Overview

The CBP3-2700BR+ is a surface-mount ceramic resonator bandpass filter from Mini-Circuits, designed for signal conditioning applications. It operates within a frequency range of 2.646 GHz to 2.754 GHz with a nominal center frequency of 2.7 GHz. The component features a 50 Ohm impedance and offers low insertion loss of 1.3 dB. It is housed in an SMD/SMT package suitable for board mounting, with a specified operating temperature range from -40°C to +85°C.

Feature Summary

• Utilizes rugged ceramic resonator construction for reliable performance
• Provides narrow bandpass filtering characteristics for precise signal selection
• Designed for surface mount integration into compact circuit boards

Applications

• RF front-end filtering in wireless communication systems
• Signal conditioning in microwave circuits
• Frequency selection in test and measurement equipment

Procurement Notes

Verify the specific suffix BR+ against official Mini-Circuits documentation to confirm packaging type and compliance status. Ensure the selected variant matches the required operational temperature range and mechanical footprint for your design. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current availability status before finalizing procurement plans.

Selection Notes

Select this component when a narrow bandwidth around 2.7 GHz is required with minimal signal attenuation. Compare its 1.3 dB insertion loss against other filters in the BFCN series if wider bandwidths are acceptable. Consider the -40°C to +85°C temperature rating for environmental suitability. Evaluate the physical dimensions of the SMD package against PCB layout constraints during the initial design phase.

Part Context

This component belongs to the CBP3 series of coaxial-ceramic resonator filters by Mini-Circuits. These filters typically offer passbands from DC up to 6GHz with fractional bandwidths ranging from less than 1% to 25%. The series is characterized by low profile designs and high stability, making them suitable for various RF and IF applications requiring precise frequency control.

Replacement Considerations

The BFCN-2700+ is a related bandpass filter from Mini-Circuits but differs in bandwidth (200 MHz) and insertion loss (5 dB). Verify if the wider bandwidth and higher loss of the BFCN-2700+ are acceptable substitutes. No other direct public substitute part numbers are confirmed for this specific model.
