BFCN-8000+

Overview

The BFCN-8000+ is an LTCC bandpass filter with a center frequency of 8 GHz and a bandwidth of 200 MHz. It operates within a 50 Ohm impedance system and features SMD/SMT termination in an FV1206-4 package (3.20mm x 1.60mm). The device supports a temperature range from -55°C to +100°C, exhibits insertion loss of 2 dB, and complies with RoHS standards.

Feature Summary

• Utilizes five-layer LTCC construction for miniature size and high performance repeatability
• Features wrap-around electrodes for enhanced signal integrity
• Designed for surface mount integration in compact RF circuits

Applications

• Wireless communication systems operating at 8 GHz
• RF front-end modules requiring precise bandpass filtering
• Test and measurement equipment

Procurement Notes

Verify the specific datasheet revision against the manufacturing date code, as product change notifications indicate potential substrate material alternates. Confirm that the FV1206-4 package dimensions align with the target PCB footprint. Ensure thermal management strategies accommodate the specified operating temperature range during final assembly.

Selection Notes

Select this component when a fixed 8 GHz center frequency with 200 MHz bandwidth is required. The 50 Ohm impedance matches standard RF transmission lines. Consider the low profile and small footprint for space-constrained designs. Verify compatibility with reflow soldering profiles suitable for LTCC materials.

Part Context

This part belongs to the Mini-Circuits BFCN family of SMT LTCC bandpass filters. These components are engineered for high reliability and consistent performance in commercial and industrial applications. The series emphasizes miniaturization without compromising electrical specifications.

Replacement Considerations

Consult official substitution lists for equivalent LTCC bandpass filters with matching 8 GHz center frequencies and 50 Ohm impedance. Verify package compatibility before replacing.
