HFCG-880+

Overview

The HFCG-880+ is a miniature high pass filter manufactured by Mini-Circuits, designed for RF and microwave applications. It utilizes Low Temperature Co-fired Ceramic (LTCC) technology to provide rugged construction suitable for dense PCB layouts with minimal performance variation due to parasitics. The component operates as a surface mount device in an 0805 package. Key electrical specifications include a cutoff frequency range of 990 MHz to 8000 MHz, a center frequency of 4.495 GHz, a bandwidth of 7.01 GHz, and an insertion loss of 1.3 dB.

Feature Summary

• Constructed using LTCC technology for ruggedness and stability in dense PCB layouts
• Designed as a high pass filter to block lower frequencies while passing higher signals
• Utilizes surface mount packaging for automated assembly compatibility

Applications

• RF signal conditioning in communication systems
• Microwave circuit design requiring high pass filtering
• Integration into dense PCB layouts where parasitic minimization is critical

Procurement Notes

Verify the specific datasheet version for the HFCG-880+ to confirm current manufacturing status and exact electrical tolerances. Ensure that the 0805 footprint dimensions align with your PCB layout constraints. Confirm that the LTCC construction meets the environmental requirements of your target application. Cross-reference the insertion loss and bandwidth specifications against system requirements before finalizing procurement decisions.

Selection Notes

Select the HFCG-880+ when a high pass filter with a cutoff starting near 990 MHz is required. Consider this component for applications needing rugged LTCC construction to handle mechanical stress. Evaluate the 1.3 dB insertion loss against system power budgets. The 0805 surface mount package is suitable for space-constrained designs. Verify that the 7.01 GHz bandwidth covers the necessary operational spectrum.
