LFCG-3500+

Overview

The Mini-Circuits LFCG-3500+ is an LTCC low-pass filter with a passband from DC to 3500 MHz. It features a compact 0805 surface-mount package and provides insertion loss of 1.3 dB. The component offers rejection levels of 35 dB at 4800-5000 MHz, 38 dB at 5000-8500 MHz, and 25 dB at 8500-15000 MHz.

Feature Summary

• Utilizes robust LTCC ceramic technology for stable performance
• Provides high signal rejection in the stopband
• Designed for compact surface-mount integration

Applications

• RF filtering in wireless communication systems
• Signal conditioning in RF test equipment
• Harmonic suppression in broadcast RF systems

Procurement Notes

Verify the specific datasheet revision when ordering, as Mini-Circuits may update electrical specifications or mechanical drawings over time. Confirm that the 0805 footprint matches your PCB layout requirements. Ensure compatibility with standard SMT reflow processes for reliable assembly. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a low-profile solution is needed for frequencies up to 3500 MHz. Consider the 1.3 dB insertion loss impact on system gain. Evaluate the stopband attenuation requirements against the specified rejection values at higher frequencies. Ensure the 0805 package size fits within the available board space constraints.

Part Context

This part belongs to the LFCG series of LTCC low-pass filters from Mini-Circuits. These components are designed for applications requiring small form factors and reliable performance in the RF spectrum. The series supports various frequency ranges while maintaining consistent electrical characteristics across the product line.

Replacement Considerations

Consult official Mini-Circuits documentation for direct substitutes. Verify that any alternative maintains the same 0805 footprint and LTCC construction to ensure mechanical compatibility.
