HFCG-650+

Overview

The HFCG-650+ is a miniature low temperature co-fired ceramic (LTCC) high pass filter designed for surface mount technology (SMT). It operates within a frequency range of 730 to 6500 MHz. Key electrical specifications include a typical insertion loss of 0.7 dB, a stop band rejection of 47 dB, and a pass band return loss of 11 dB. The component utilizes an SMD-6P package with dimensions of 2x1.3mm.

Feature Summary

• Constructed using low temperature co-fired ceramic (LTCC) technology for robust signal conditioning
• Designed as a surface mount device (SMT) for compact circuit integration
• Provides high pass filtering functionality with specified stop band rejection

Applications

• RF signal conditioning in electronic circuits
• High-frequency signal filtering applications
• Miniature RF system design requiring SMT components

Procurement Notes

Verify the specific datasheet version when sourcing, as Mini-Circuits may update electrical tolerances or packaging details over time. Confirm that the LTCC construction and SMD-6P package dimensions align with your PCB layout requirements. Ensure compatibility with standard reflow soldering profiles for 0805-style footprints. Cross-reference the 730-6500 MHz operating range against your system's frequency needs to confirm adequate stop band performance.

Selection Notes

Select this component when a miniature high pass filter is required for frequencies starting at 730 MHz. The LTCC construction offers reliability suitable for various environmental conditions. Consider the 0.7 dB typical insertion loss if signal integrity is critical. The small 2x1.3mm footprint makes it ideal for space-constrained designs compared to larger through-hole alternatives.
