BFCN-4440+

Overview

The BFCN-4440+ is a ceramic band pass filter manufactured by Mini-Circuits, designed for RF applications. It operates within a frequency range of 4200 to 4700 MHz with a center frequency of 4400 MHz and a bandwidth of 500 MHz. The component features a 50 Ohm impedance and utilizes LTCC technology for compact construction. It is housed in an FV1206 surface-mount package (4-SMD, No Lead) suitable for automated assembly.

Feature Summary

• Constructs multiple layers using LTCC technology to achieve a miniature physical size while maintaining signal integrity.
• Provides EMI and RFI suppression capabilities through precise band pass filtering characteristics.
• Designed for high-performance S-band upconverter assemblies and general RF signal conditioning.

Applications

• S-band frequency upconverter designs
• EMI/RFI suppression circuits
• Signal filtering in wireless communication systems

Procurement Notes

Verify the specific datasheet version and revision date before procurement, as Mini-Circuits may update specifications over time. Confirm that the FV1206 package dimensions align with your PCB footprint requirements. Ensure compatibility with standard reflow soldering profiles for 4-SMD no-lead components. Check for any recent changes in RoHS compliance status or material composition if required by your manufacturing standards.

Selection Notes

Select this component when a fixed 500 MHz bandwidth centered at 4400 MHz is required in a minimal footprint. The LTCC construction offers stability compared to discrete LC solutions. Consider the FV1206 case style for space-constrained designs. Evaluate insertion loss and rejection levels against system noise floor requirements. This part is suitable for applications demanding reliable performance in the S-band spectrum without bulky packaging.
