BFCN-1801+

Overview

The BFCN-1801+ is a surface-mount LTCC bandpass filter designed for RF applications. It operates with a center frequency of 1.801 GHz and provides a bandwidth of 920 MHz, covering the range from 1400 MHz to 2320 MHz. The component features a 50 Ohm impedance and utilizes a compact 1206 (3216 Metric) package measuring 3.20mm x 1.6 mm. Its wrap-around terminations ensure high performance repeatability while minimizing parasitic effects.

Feature Summary

• Utilizes Low-Temperature Co-fired Ceramic (LTCC) technology for miniature size and high performance repeatability
• Features wrap-around terminations to minimize variations in performance and reduce parasitic effects
• Provides rejection peaks close to the passband for effective signal conditioning

Applications

• S-band upconverter assemblies
• RF signal conditioning circuits
• High-density circuit board layouts requiring small form factors

Procurement Notes

Verify the specific part number suffix against official Mini-Circuits documentation to confirm exact specifications. Ensure compatibility with standard SMT assembly processes given the 1206 package dimensions. Cross-reference impedance requirements to match the 50 Ohm system design. Confirm that the operating temperature range meets application needs before finalizing procurement orders.

Selection Notes

Select this component when a compact bandpass filter is required for the 1.4 GHz to 2.32 GHz range. The 1206 footprint supports high layout density compared to larger ceramic filters. Consider the LTCC construction for improved thermal stability and mechanical robustness in surface-mount environments where space constraints are critical.

Part Context

This component belongs to Mini-Circuits' broad selection of MMIC components and passive filters. It is part of a family of LTCC bandpass filters designed for chip and wire integration or direct surface mounting. The product line spans DC to mmWave frequencies, offering various models for diverse RF and microwave applications.

Replacement Considerations

Consult official Mini-Circuits substitution guides for verified alternatives. Generic cross-references may not account for specific LTCC material properties or termination styles. Verify that any substitute maintains the 1206 package outline and 50 Ohm impedance to ensure board compatibility.
