BFCN-1900+

Overview

The BFCN-1900+ is a ceramic bandpass filter manufactured by Mini-Circuits, designed for RF applications. It operates with a center frequency of 1.9 GHz and features a bandwidth of 27 MHz. The component supports a 50 Ohm impedance environment and utilizes an LTCC construction method. It is housed in a compact FV1206-5 surface-mount package, suitable for automated assembly processes.

Feature Summary

• LTCC construction for reliable high-frequency performance
• Surface-mount design for automated PCB integration
• Defined passband characteristics for signal selection

Applications

• RF front-end filtering
• Wireless communication systems
• EMI/RFI suppression circuits

Procurement Notes

Verify the specific datasheet revision and electrical test conditions provided by Mini-Circuits before finalizing designs. Confirm that the FV1206-5 package dimensions align with your PCB footprint requirements. Ensure compatibility with standard SMT reflow profiles to maintain component integrity during assembly.

Selection Notes

Select this component when a fixed 1.9 GHz center frequency with narrow bandwidth is required. The 50 Ohm impedance matches standard RF transmission lines. Consider the LTCC technology for stability in varying thermal environments compared to other ceramic types.

Part Context

This part belongs to Mini-Circuits' BFCN series of ceramic filters. These components are engineered for general-purpose RF filtering tasks. The series offers various center frequencies to suit different wireless standards. The BFCN-1900+ specifically targets the 1.9 GHz ISM band applications.

Replacement Considerations

Check Mini-Circuits documentation for direct cross-references. Verify that any substitute maintains the 1893-1920 MHz passband range. Ensure the replacement package matches the FV1206-5 form factor for board compatibility.
