HFCN-650D+

Overview

The HFCN-650D+ is a low-temperature co-fired ceramic (LTCC) high-pass filter manufactured by Mini-Circuits. It operates within the ultra-wideband range of 29GHz to 56.2GHz, with a specific cutoff frequency centered at 1.78 GHz. The device features a 50 Ohm impedance and utilizes a 4-SMD, no lead package configuration. Its physical dimensions are specified as 3.2mm x 1.6mm x 0.94mm, corresponding to the FV1206 case style. The component ensures a minimum DC resistance to ground of 100 Mohms.

Feature Summary

• Constructed using low-temperature co-fired ceramic (LTCC) technology for robust performance in ultra-wideband applications.
• Designed as a high-pass filter with a center frequency of 1.78 GHz and 50 Ohm impedance.
• Utilizes a compact 4-SMD, no lead surface-mount package for efficient integration.

Applications

• Ultra-wideband RF signal processing systems
• Microwave communication circuits requiring high-frequency filtering
• RF front-end modules operating above 1.78 GHz

Procurement Notes

Verify the exact datasheet specifications against the manufacturer's official documentation before procurement. Confirm that the LTCC construction and SMD package type align with your PCB design requirements. Ensure compatibility with the 50 Ohm system impedance and validate thermal management needs for the small form factor. Cross-reference the part number suffix to confirm it matches the intended high-pass filter variant.

Selection Notes

Select this component when a high-pass filter with a 1.78 GHz cutoff is required in an ultra-wideband context. The LTCC technology offers stability across wide frequency ranges up to 56.2GHz. Consider the FV1206 footprint for space-constrained designs. Verify that the 50 Ohm impedance matches your system architecture and that the surface-mount format suits your assembly process.
