BFCG-252+

Overview

The Mini-Circuits BFCG-252+ is a Low Temperature Co-fired Ceramic (LTCC) bandpass filter designed for radio frequency signal conditioning. It operates within a passband of 2400 to 2500 MHz, centered on the 2.4 GHz ISM band. The component features a 50 Ohm impedance and is housed in a compact 0805 surface-mount package. Typical insertion loss is specified at 1.7 dB, with some sources citing up to 3.5 dB depending on measurement conditions.

Feature Summary

• Utilizes LTCC technology for robust ceramic construction
• Optimized for 2.4 GHz ISM band applications
• Compact 0805 surface-mount footprint

Applications

• Wireless communication systems
• ISM band signal filtering
• RF front-end modules

Procurement Notes

Verify the specific datasheet version when ordering, as insertion loss specifications may vary between 1.7 dB and 3.5 dB across different documentation releases. Confirm the 0805 package dimensions match your PCB layout requirements. Ensure compatibility with standard SMT reflow processes for LTCC components.

Selection Notes

Select this component for applications requiring a narrow bandpass filter specifically tuned to the 2400–2500 MHz range. The 0805 package size offers a balance between performance and board space efficiency. Consider the typical insertion loss when designing for low-noise signal paths.

Part Context

This part belongs to the BFCG series from Mini-Circuits, which focuses on compact ceramic filters. Related models include balun-integrated variants like the BBFCG1-252+ and BBFCG2-252+, which offer impedance transformation capabilities alongside filtering functions for differential or single-ended interface needs.

Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Evaluate other Mini-Circuits BFCG series parts for similar bandwidths. Verify that any alternative maintains the 0805 footprint and 50 Ohm impedance to ensure mechanical and electrical compatibility.
