HFCN-8400D+

Overview

The HFCN-8400D+ is a high-pass ceramic filter manufactured by Mini-Circuits, utilizing low-temperature co-fired ceramic (LTCC) technology. It features a center frequency of 11 GHz and a bandwidth of 4 GHz. The component operates at a system impedance of 50 Ohms and is housed in a compact 6-SMD, no-lead package with dimensions of 3.20mm x 1.60mm x 1.07mm maximum height. Designed for surface mount installation, it supports frequencies up to 56.2 GHz within the broader HFCN series range.

Feature Summary

• Constructed using low-temperature co-fired ceramic (LTCC) technology for reliable microwave performance.
• Provides high-pass filtering characteristics with a defined 4 GHz bandwidth centered at 11 GHz.
• Features a compact 6-SMD no-lead surface mount package suitable for automated assembly.

Applications

• Microwave frequency signal conditioning
• Ultra-wideband RF circuit integration
• High-frequency interference suppression

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as HFCN-8400+ and HFCN-8400D+ exist within the same product family. Confirm that the required packaging format aligns with available options like tape and reel or cut tape. Ensure compatibility with standard LTCC processing temperatures during PCB assembly to maintain component integrity and electrical specifications.

Selection Notes

Select this component for applications requiring precise high-pass filtering in the 9 GHz to 13 GHz range. The 50 Ohm impedance matches standard RF transmission lines. Consider the physical footprint constraints due to the small SMD package size. Verify that the operating environment does not exceed the thermal limits specified for LTCC materials. Ensure the design accounts for the specific attenuation characteristics provided in the official datasheet graphs.

Part Context

This component belongs to the HFCN series of LTCC high-pass filters from Mini-Circuits. The series covers an ultra-wideband frequency range from 29 GHz to 56.2 GHz. The HFCN-8400D+ specifically targets the lower end of this spectrum relative to other series members, offering a 11 GHz center frequency. It shares common construction materials and mounting styles with other parts in the lineup.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult Mini-Circuits engineering support for direct equivalents or cross-references if the HFCN-8400D+ is unavailable. Ensure any alternative component meets the same 50 Ohm impedance and 6-SMD package requirements.
