HFCN-1810D+

Overview

The HFCN-1810D+ is a ceramic high-pass filter from Mini-Circuits, designed for ultra-wideband applications between 29 GHz and 56.2 GHz. It features a center frequency of 3.35 GHz with a cutoff at 2.8 GHz. The component operates at a standard impedance of 50 Ohms and utilizes a 4-SMD, no-lead package. Electrical specifications are measured at +25°C on the TB-HFCN-1810D+ characterization test board. The device ensures a minimum DC resistance to ground of 100 Mohms.

Feature Summary

• Constructed using low-temperature co-fired ceramic (LTCC) technology for robust performance.
• Designed specifically for dense signal chain PCB layouts to complement MMICs.
• Suitable for operation in harsh environments, including conditions with high humidity.

Applications

• Ultra-wideband RF systems
• S-band upconverter assemblies
• High-frequency signal filtering

Procurement Notes

Verify the exact part number suffix against official Mini-Circuits documentation to ensure correct specifications. Confirm that the required operating temperature range aligns with the component's maximum rating of +100 C. Ensure compatibility with the 4-SMD, no-lead package footprint during PCB design. Cross-reference datasheet electrical parameters measured at +25°C for accurate system modeling.

Selection Notes

Select this component when a high-pass filter is required for frequencies extending into the millimeter-wave range. The LTCC construction provides stability suitable for demanding environments. Consider the 50 Ohm impedance match for integration into standard RF chains. Verify that the physical dimensions of the 4-SMD package fit within the available PCB space constraints.
