BFCN-1840+

Overview

The BFCN-1840+ is a surface-mount LTCC bandpass filter designed for RF signal conditioning. It features a center frequency of 1.84 GHz with a bandwidth of 180 MHz, covering the range from 1750 to 1930 MHz. The component operates within a 50-ohm impedance system and utilizes an FV1206 package (3.2mm x 1.6mm). It supports SMD/SMT termination and functions reliably across a temperature range of -55°C to +100°C.

Feature Summary

• Low insertion loss performance for efficient signal transmission
• Good out-of-band rejection characteristics
• Compact LTCC construction suitable for space-constrained designs

Applications

• Wireless communication systems requiring 1.84 GHz filtering
• RF front-end modules in mobile devices
• Industrial, Scientific, and Medical (ISM) equipment operating near 1.84 GHz

Procurement Notes

Verify the specific datasheet version when ordering, as Mini-Circuits may update specifications. Confirm that the FV1206 footprint matches your PCB layout exactly. Ensure the supplier provides RoHS compliance documentation if required by your manufacturing standards. Check for any specific handling instructions related to the ceramic substrate during assembly.

Selection Notes

Select this component when a narrow bandpass response centered at 1.84 GHz is required. The 180 MHz bandwidth defines the passband limits between 1750 and 1930 MHz. Consider the FV1206 size constraint against available board space. Verify that the 50-ohm system impedance aligns with your circuit design requirements before integration.

Part Context

This part belongs to the BFCN series of LTCC bandpass filters from Mini-Circuits. These components are engineered for high reliability in RF applications. The series offers various center frequencies while maintaining consistent package dimensions and electrical performance profiles typical of ceramic filter technology.

Replacement Considerations

Check Mini-Circuits documentation for direct substitutes within the BFCN series. Verify that alternative parts match the 1.84 GHz center frequency and 180 MHz bandwidth. Ensure physical compatibility with the FV1206 footprint if swapping manufacturers.
