BFCN-1860+

Overview

The BFCN-1860+ is an LTCC bandpass filter manufactured by Mini-Circuits. It operates within a frequency range of 1580 to 2200 MHz, providing a bandwidth centered on the L-band and S-band spectrum. The component features a nominal insertion loss of 2 dB and offers 20 dB rejection in both upper and lower stopbands. Designed for robust performance, it utilizes Low-Temperature Co-fired Ceramic construction housed in a compact FV1206-4 surface-mount package. The device maintains a standard 50 Ohm impedance and is suitable for board mounting applications requiring precise signal filtering.

Feature Summary

• LTCC construction provides ruggedness suitable for high humidity and temperature extremes
• Compact surface-mount footprint enables efficient PCB space utilization
• Provides defined passband with specified stopband rejection characteristics

Applications

• L-band and S-band communication systems
• RF front-end filtering modules
• Wireless infrastructure components

Procurement Notes

Verify the specific datasheet version and manufacturer documentation to confirm electrical parameters and mechanical dimensions before integration. Ensure compatibility with standard surface-mount assembly processes. Confirm that the 50 Ohm impedance matches system requirements. Validate thermal performance against application environmental conditions. Cross-reference part numbers to avoid counterfeit components.

Selection Notes

Select this component when a narrow bandpass response between 1580 and 2200 MHz is required. Consider the LTCC technology for durability in harsh environments. Evaluate the insertion loss specification against link budget requirements. Assess the physical size constraints of the target PCB layout. Verify that the stopband rejection meets interference mitigation needs.
