HFCG-4400+

Overview

The HFCG-4400+ is a miniature low temperature co-fired ceramic (LTCC) high pass filter manufactured by Mini-Circuits. It features a passband from 4900 MHz to 18500 MHz with a 50 Ohm impedance. The component utilizes a surface mount package, specifically the GE0805C-9 case style, designed for integration into compact RF circuits.

Feature Summary

• Constructed using low temperature co-fired ceramic (LTCC) technology for robust performance
• Designed as a miniature surface mount device for space-constrained applications
• Provides very good rejection characteristics outside the passband

Applications

• RF front-end filtering in microwave systems
• Harmonic suppression in communication transceivers
• Signal conditioning in test and measurement equipment

Procurement Notes

Verify the specific datasheet version and mechanical dimensions against your PCB layout requirements. Confirm that the LTCC construction and SMD package type align with your assembly capabilities. Ensure the frequency range meets your system's spectral needs before finalizing procurement.

Selection Notes

Select this component when a high pass filter with a cutoff near 4.9 GHz is required. Consider the LTCC material properties for thermal stability. Evaluate the physical footprint compatibility with your design constraints. Verify impedance matching at the operating frequencies to ensure optimal signal transmission.

Part Context

This part belongs to Mini-Circuits' HFCG series of LTCC high pass filters. These components are engineered for RF, IF, and microwave applications ranging from DC to 86GHz. The series offers various cutoff frequencies to suit different filtering requirements in modern electronic designs.

Replacement Considerations

Consult Mini-Circuits for qualified alternate ceramic substrate materials or equivalent LTCC high pass filters with similar cutoff frequencies and package styles.
