HFCG-2100+

Overview

The HFCG-2100+ is a ceramic high-pass filter manufactured by Mini-Circuits, designed for RF signal conditioning applications. It operates within a frequency range of 2200 MHz to 6000 MHz and features a center frequency of 4.1 GHz. The component utilizes LTCC technology and is housed in the GE0805C-2 surface-mount package. It maintains a standard impedance of 50Ω and functions reliably across an operating temperature range of -55°C to +125°C.

Feature Summary

• Utilizes Low-Temperature Co-fired Ceramic (LTCC) construction for robust performance
• Provides high-pass filtering characteristics with defined cutoff frequencies
• Designed for surface-mount integration via compact GE0805C-2 package

Applications

• RF signal conditioning in communication systems
• S-band upconverter assemblies
• Microwave circuit design requiring high-pass filtering

Procurement Notes

Verify the specific datasheet version when ordering, as Mini-Circuits may update technical specifications over time. Confirm that the GE0805C-2 package dimensions align with your PCB layout requirements. Ensure that the operating temperature range of -55°C to +125°C meets your environmental constraints. Cross-reference the 50Ω impedance specification with your system interface to guarantee proper matching.

Selection Notes

Select this component when a high-pass filter is required for frequencies above 2200 MHz. The LTCC construction offers stability suitable for demanding environments. Consider the 4.1 GHz center frequency for applications targeting the S-band or similar microwave ranges. The surface-mount format facilitates automated assembly processes.

Part Context

Mini-Circuits specializes in RF, IF, and microwave components ranging from DC to 86 GHz. The HFCG series represents their line of ceramic filters, which are engineered for reliability and consistent performance in various signal processing roles. This specific model integrates into broader system designs where precise frequency selection is critical.

Replacement Considerations

Consult official Mini-Circuits documentation for direct substitutes. Verify that any alternative component matches the 2200-6000 MHz passband and 50Ω impedance. Ensure physical compatibility with the GE0805C-2 footprint if board space is constrained.
