LFCG-3000+

Overview

The Mini-Circuits LFCG-3000+ is an LTCC low-pass filter with a passband from DC to 3000 MHz. It features a typical insertion loss of 1.1 dB and a maximum of 2.2 dB at 3.46 GHz. The component operates at 50 Ω impedance in an 0805 (2012 Metric) surface-mount package.

Feature Summary

• Utilizes Low Temperature Co-fired Ceramic (LTCC) technology for compact integration
• Provides high rejection levels up to 50 dB in the stopband
• Designed for surface-mount assembly in small form factors

Applications

• RF and microwave communication systems
• Signal conditioning in wireless infrastructure
• Frequency filtering in test and measurement equipment

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status before procurement. Confirm that the 0805 footprint matches your PCB layout requirements. Ensure the operating frequency range aligns with your system's signal spectrum to avoid performance degradation due to mismatched cutoff characteristics.

Selection Notes

Select this component when a compact, high-rejection low-pass filter is required for frequencies up to 3000 MHz. The LTCC construction offers stability in harsh environments. Consider the 0805 package size for space-constrained designs requiring surface-mount compatibility without sacrificing filtering performance.

Part Context

This part belongs to the Mini-Circuits LFCG series, which specializes in tiny 0805-sized low-pass filters. The series supports frequency ranges up to 6100 MHz with high rejection capabilities. These components are engineered for modern RF applications demanding miniaturization and reliable signal integrity in dense circuit layouts.

Replacement Considerations

Check for direct substitutes within the LFCG series with similar cutoff frequencies. Verify pinout compatibility and thermal characteristics if replacing in existing designs. Consult official manufacturer cross-reference lists for validated alternatives.
