BFCQ-2872+

Overview

The BFCQ-2872+ is a signal conditioning LTCC bandpass filter manufactured by Mini-Circuits. It operates within a frequency range of 27,500 MHz to 30,000 MHz with a center frequency of 28.7 GHz. The component features a nominal impedance of 50 Ohms and utilizes a 3-SMD surface-mount package. Its physical dimensions are 2.50 mm in length and 2.00 mm in width. The device is compliant with RoHS and REACH standards.

Feature Summary

• Utilizes proprietary LTCC material system for high performance repeatability
• Miniature size enables high circuit board layout density
• Minimizes parasitic effects through compact design

Applications

• Very high frequency circuit applications
• Signal conditioning systems requiring precise bandpass filtering
• High-density electronic assemblies

Procurement Notes

Verify the specific datasheet version and compliance documentation directly from Mini-Circuits or authorized distributors before procurement. Ensure that the 3-SMD package footprint matches the target PCB design constraints. Confirm that the operating environment supports the specified temperature and frequency ranges defined in the official technical specifications.

Selection Notes

Select this component when a fixed 27.5 GHz to 30 GHz passband is required for signal integrity. The choice is driven by the need for miniature SMT packaging and consistent LTCC performance. Consider the 50 Ohm impedance match for system compatibility. Evaluate the physical space constraints against the 2.5mm x 2.0mm dimensions.

Part Context

This part belongs to the Mini-Circuits BFCQ series of ceramic filters. These components are designed for microwave and millimeter-wave applications. The series emphasizes small form factors and reliable performance in demanding RF environments. The BFCQ-2872+ specifically targets the 28-30 GHz spectrum segment.

Replacement Considerations

Consult Mini-Circuits official substitution guides for verified alternatives. Cross-reference electrical parameters such as insertion loss and rejection characteristics. Ensure mechanical compatibility with the existing 3-SMD footprint if replacing on an active board.
