HFCN-5500D+

Overview

The HFCN-5500D+ is a high-pass ceramic filter manufactured by Mini-Circuits. It features a center frequency of 8.75 GHz and a bandwidth of 5.5 GHz. The component operates at a nominal impedance of 50 Ohms and utilizes a 6-SMD, no-lead surface-mount package with dimensions of 3.20mm x 1.60mm x 1.07mm. It is constructed using low-temperature co-fired ceramic (LTCC) technology and is RoHS3 compliant.

Feature Summary

• Utilizes low-temperature co-fired ceramic (LTCC) construction for robust performance in ultra-wideband applications.
• Designed as a high-pass filter to allow frequencies above the cutoff while attenuating lower signals.
• Features a compact 6-SMD no-lead surface-mount package suitable for automated assembly.

Applications

• RF front-end filtering in microwave communication systems
• Signal conditioning in ultra-wideband test equipment
• Harmonic suppression in high-frequency transmitter chains

Procurement Notes

Verify the specific suffix 'D' against official Mini-Circuits documentation to confirm package and tape-and-reel specifications. Ensure compatibility with standard LTCC handling procedures due to ceramic substrate sensitivity. Cross-reference the part number with current datasheets to validate any recent material alternations or design changes.

Selection Notes

Select this component when a high-pass response centered at 8.75 GHz is required within the 29GHz to 56.2GHz operational range of the HFCN series. Consider the 50 Ohm impedance match for system integration. Evaluate the physical footprint constraints against the 1206-style case size before finalizing the PCB layout.

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 29GHz to 56.2GHz. The HFCN-5500D+ specifically targets applications requiring filtering around the 8.75 GHz center frequency with a defined bandwidth.

Replacement Considerations

Consult Mini-Circuits official substitution guides for equivalent high-pass filters within the HFCN series. Verify that alternative parts maintain the same 50 Ohm impedance and compatible surface-mount package dimensions for direct board replacement.
