HFCN-8400+

Overview

The HFCN-8400+ 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 standard impedance of 50 Ohms and is housed in a compact 6-SMD, no-lead surface-mount package with dimensions of 3.20mm x 1.60mm x 1.07mm. Designed for robust performance, it supports a wide operating temperature range from -55°C to +100°C. This filter effectively suppresses low-frequency interference while maintaining signal integrity in high-frequency applications.

Feature Summary

• Utilizes LTCC technology for compact SMD packaging and low temperature drift
• Effectively suppresses RF clutter, harmonics, and low-frequency interference
• Ensures high signal integrity in multi-band RF filtering designs

Applications

• Multi-band RF filtering in wireless devices
• Suppression of high-frequency harmonics in RF systems
• Mitigation of low-frequency interference in microwave circuits

Procurement Notes

Verify the specific datasheet version when sourcing, as alternate qualified ceramic substrate materials may be utilized per product change notices. Confirm RoHS3 compliance status during procurement. Ensure the ordering suffix matches the required packaging format, such as tape and reel or cut tape, to align with assembly line requirements. Cross-reference the manufacturer part number against distributor listings to confirm current availability and lead times.

Selection Notes

Select this component for applications requiring a high-pass response centered at 11 GHz with a 4 GHz bandwidth. The 50 Ohm impedance rating ensures compatibility with standard RF transmission lines. The surface-mount package facilitates automated assembly and space-constrained PCB layouts. Consider the operating temperature range of -55°C to +100°C for environmental suitability in industrial or outdoor deployments.
