LFCG-4800+

Overview

The LFCG-4800+ is a low-pass filter manufactured by Mini-Circuits, utilizing LTCC technology in a compact 0805 surface-mount package. It provides a passband from DC to 4800 MHz with a cutoff frequency of 5.6 GHz and a nominal impedance of 50 Ohms. The component exhibits an insertion loss of approximately 1.2 dB within the passband and offers rejection levels up to 50 dB. It operates reliably across a temperature range of -55°C to +125°C.

Feature Summary

• Compact 0805 surface-mount footprint for space-constrained designs
• High rejection capability up to 50 dB above cutoff
• Wide bandwidth coverage from DC to 4800 MHz
• Robust thermal performance suitable for harsh environments

Applications

• RF signal conditioning in communication systems
• Harmonic suppression in RF circuits
• Base station front-end filtering
• Test and measurement equipment

Procurement Notes

Verify the specific datasheet version when sourcing, as specifications may vary slightly between revisions. Confirm that the 0805 package dimensions align with your PCB layout constraints. Ensure the operating temperature range meets your environmental requirements, as this component supports extended industrial temperatures. Cross-reference the manufacturer's part number to avoid confusion with similar series components.

Selection Notes

Select this component when a small form factor is critical alongside high-frequency filtering needs. The 5.6 GHz cutoff makes it suitable for applications requiring attenuation of higher-order harmonics while preserving signals up to 4.8 GHz. Consider the LTCC construction for stability and reliability in demanding RF environments compared to other filter technologies.

Part Context

This component belongs to the LFCG series of low-pass filters from Mini-Circuits. The series is characterized by its use of LTCC technology and availability in small surface-mount packages. These filters are designed to provide consistent performance in RF applications where size and rejection characteristics are prioritized.

Replacement Considerations

Check for direct substitutes within the same LFCG series or comparable LTCC low-pass filters from Mini-Circuits. Verify that any alternative maintains the 0805 package size and similar electrical parameters, such as cutoff frequency and impedance, to ensure compatibility without redesigning the circuit board.
