HFCG-3800+

Overview

The HFCG-3800+ is an LTCC high-pass filter with a cutoff frequency of 3.8 GHz and a passband from 4200 MHz to 18000 MHz. It operates at 50 Ohms impedance, offering 1 dB typical insertion loss and 1.5 dB bandwidth. The component utilizes GE0805C-9 surface-mount packaging for dense PCB layouts.

Feature Summary

• Utilizes rugged LTCC construction for minimal performance variation due to parasitics in dense layouts
• Provides high-pass filtering characteristics with specified cutoff and passband frequencies
• Designed for signal conditioning applications requiring stable RF performance

Applications

• RF signal conditioning
• Microwave circuit design
• S-band upconverter assemblies

Procurement Notes

Verify the exact part number suffix against official Mini-Circuits documentation to ensure correct specifications. Confirm package style and electrical parameters match system requirements before ordering. Cross-reference datasheets for precise insertion loss and bandwidth values.

Selection Notes

Select this component for applications requiring high-pass filtering above 3.8 GHz. Ensure the operating environment supports the specified frequency range up to 18 GHz. Consider the surface-mount package dimensions for PCB layout compatibility.

Part Context

This component belongs to Mini-Circuits' LTCC filter series, designed for RF and microwave applications. It complements other passive components like low-pass filters and mixers in complex signal processing systems.

Replacement Considerations

Consult official Mini-Circuits substitution guides for verified alternatives. Generic equivalents may not match LTCC construction or specific parasitic performance characteristics.
