HFCG-1600+

Overview

The HFCG-1600+ is an LTCC high-pass filter manufactured by Mini-Circuits, designed for RF applications. It features a passband from 1650 MHz to 5000 MHz with a cutoff frequency of 1600 MHz. The component operates at a nominal impedance of 50 Ohms and utilizes a GE0805C-2 surface-mount package. Constructed with ceramic materials, it offers high power handling capabilities and high rejection characteristics suitable for dense PCB layouts.

Feature Summary

• LTCC construction provides ruggedness and minimal performance variation due to parasitics in dense PCB layouts
• High power handling capability ensures reliable operation under demanding signal conditions
• High rejection characteristics effectively suppress unwanted low-frequency signals outside the passband

Applications

• RF front-end filtering in communication systems
• Signal conditioning in microwave circuits
• Interference suppression in high-density electronic assemblies

Procurement Notes

Verify the specific ordering suffix against official Mini-Circuits documentation to ensure correct configuration. Confirm that the requested variant matches the required tolerance and termination specifications. Cross-reference the datasheet revision date to guarantee compatibility with current design standards. Ensure the procurement channel sources directly from authorized distributors to maintain component integrity and traceability.

Selection Notes

Select this component when a high-pass response starting at 1600 MHz is required within the 1650-5000 MHz range. The GE0805C-2 package suits space-constrained designs. Consider the LTCC technology for improved thermal stability and mechanical robustness compared to standard ceramic filters. Evaluate insertion loss and return loss parameters against system requirements before finalizing the design integration.

Part Context

This part belongs to Mini-Circuits' HFCG series of LTCC high-pass filters. The series is characterized by its compact size and robust ceramic construction. These filters are engineered for consistent performance across varying environmental conditions. The HFCG-1600+ specifically targets applications requiring precise high-frequency signal passage while attenuating lower frequencies.

Replacement Considerations

Consult Mini-Circuits official substitution guides for compatible alternatives. Verify electrical parameter equivalence including cutoff frequency and impedance. Ensure physical footprint compatibility if board space is limited. Check manufacturer availability and lead times for potential supply chain adjustments.
