LFCN-8400+

Overview

The LFCN-8400+ is a surface-mount LTCC low-pass filter with a DC to 8.4 GHz passband and a 9.1 GHz cutoff frequency. It operates at 50 Ohms impedance with 1.6 dB insertion loss. The component features a compact FV1206-4 package, supports space qualification standards, and includes an internal termination for absorptive performance.

Feature Summary

• Utilizes LTCC technology for high reliability in harsh environments
• Provides absorptive characteristics via internal termination
• Designed for space-qualified applications requiring robust RF filtering

Applications

• Satellite communication systems
• Space-qualified RF front ends
• Microwave signal conditioning

Procurement Notes

Verify the specific suffix designation against official Mini-Circuits documentation to confirm exact electrical tolerances and space qualification status. Ensure the ordering code matches the required package variant and termination specifications before procurement.

Selection Notes

Select this component when a low-profile, space-rated low-pass filter is required for frequencies up to 8.4 GHz. The absorptive design minimizes reflection issues, making it suitable for sensitive RF chains where signal integrity is critical.

Part Context

This part belongs to Mini-Circuits' LTCC ceramic filter family, designed for microwave and millimeter-wave applications. The series offers various cutoff frequencies while maintaining consistent 50 Ohm impedance and surface-mount compatibility for automated assembly.

Replacement Considerations

Consult official substitution guides for equivalent LTCC low-pass filters with matching cutoff frequencies and package dimensions. Verify that any alternative meets the same space qualification requirements if applicable.
