BFCN-1945+

Overview

The Mini-Circuits BFCN-1945+ is an LTCC bandpass filter designed for surface mount applications. It operates with a center frequency of 1945 MHz and a bandwidth of 190 MHz, covering the range from 1850 to 2040 MHz. The component features a 50Ω impedance and utilizes a compact FV1206 package measuring 3.2mm x 1.6mm. Constructed with 12 layers, it offers low insertion loss and good rejection characteristics suitable for RF signal conditioning.

Feature Summary

• Utilizes Low-Temperature Co-fired Ceramic (LTCC) technology for high performance repeatability
• Provides effective signal filtering within the specified 1850–2040 MHz passband
• Features a miniature surface-mount footprint for space-constrained designs

Applications

• RF front-end modules requiring bandpass filtering
• Wireless communication systems operating in the S-band
• Signal conditioning circuits for upconverter assemblies

Procurement Notes

Verify the specific datasheet revision and electrical test data prior to integration. Confirm that the FV1206 package dimensions align with your PCB layout constraints. Ensure compatibility with standard reflow soldering profiles for LTCC components. Cross-reference the part number suffix to confirm RoHS compliance status as documented by the manufacturer.

Selection Notes

Select this component when a narrow bandpass response centered at 1945 MHz is required. The 50Ω design ensures direct integration into standard RF transmission lines without additional matching networks. Consider the physical size relative to available board space, as the FV1206 package is optimized for miniaturization while maintaining electrical integrity in high-frequency applications.
