BFCN-2850+

Overview

The BFCN-2850+ is a ceramic bandpass filter manufactured by Mini-Circuits, designed for RF applications. It features a center frequency of 2850 MHz with a bandwidth of 200 MHz, operating within a 2.75 to 2.95 GHz range. The component exhibits an insertion loss of 4 dB and is rated for 50 Ohm impedance. It utilizes LTCC construction for miniature size and high performance repeatability.

Feature Summary

• LTCC construction for compact form factor
• High performance repeatability
• Miniature surface-mount design

Applications

• RF signal conditioning
• Wireless communication systems
• IF filtering stages

Procurement Notes

Verify the specific datasheet version from Mini-Circuits or authorized distributors to confirm current manufacturing status and exact electrical tolerances. Ensure compatibility with 50 Ohm system impedance before integration. Check for RoHS compliance markings on packaging if required by project specifications.

Selection Notes

Select this component when a narrow 200 MHz bandwidth centered at 2.85 GHz is required in a small footprint. The LTCC technology offers stability suitable for mass production. Compare insertion loss specifications against system link budget requirements to ensure adequate signal integrity.

Part Context

This part belongs to Mini-Circuits' family of LTCC bandpass filters. These components are engineered for high reliability in microwave and RF circuits. The series provides consistent performance across temperature variations, making them suitable for commercial and industrial electronic applications requiring precise frequency selection.

Replacement Considerations

Direct substitutes may include other Mini-Circuits LTCC bandpass filters with similar center frequencies and bandwidths. Verify pinout compatibility and physical dimensions before swapping. Consult manufacturer cross-reference lists for equivalent parts with adjusted electrical characteristics.
