BFCO-552+

Overview

The BFCO-552+ is a low-temperature co-fired ceramic (LTCC) bandpass filter manufactured by Mini-Circuits. It operates with a center frequency of 5.5 GHz and provides a passband range from 4600 MHz to 6100 MHz. The component features a 50 Ohm impedance and utilizes the NK0402C-1 surface-mount package, measuring 1.0 mm in length, 0.5 mm in width, and 0.43 mm in height. Electrical specifications include a maximum insertion loss of 2.2 dB and a minimum stopband attenuation of 40 dB at frequencies outside the passband.

Feature Summary

• Utilizes LTCC technology for compact surface-mount integration
• Provides defined bandpass filtering between 4600 MHz and 6100 MHz
• Designed for 50 Ohm RF system environments

Applications

• Wireless communication systems operating in the 5 GHz range
• RF front-end modules requiring signal band selection
• Microwave circuitry for interference rejection

Procurement Notes

Verify the specific datasheet revision and test conditions when evaluating performance metrics. Confirm that the NK0402C-1 footprint matches your PCB layout requirements. Ensure compatibility with standard surface-mount assembly processes. Cross-reference electrical specifications against your system's tolerance levels for insertion loss and attenuation before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 5.5 GHz center frequency is required within a 1.5 GHz bandwidth. The LTCC construction offers stability suitable for microwave applications. Consider the physical dimensions of the 0402 metric package for space-constrained designs. Verify that the 50 Ohm impedance aligns with your transmission line characteristics to minimize reflection losses.

Part Context

This part belongs to Mini-Circuits' BFCO series of LTCC bandpass filters. These components are engineered for high-reliability RF and microwave applications. The series typically covers various frequency bands using standardized surface-mount packages. The BFCO-552+ specifically addresses needs in the 5 GHz spectrum, offering a balance between size and performance for modern wireless infrastructure.

Replacement Considerations

Consult official Mini-Circuits documentation for direct substitutes. Verify that any alternative maintains identical center frequency, bandwidth, and impedance. Ensure package compatibility if swapping footprints is not feasible. Check for updated revisions or superseded part numbers in manufacturer catalogs.
