LFCG-3800+

Overview

The Mini-Circuits LFCG-3800+ is an LTCC low-pass filter with a passband from DC to 3900 MHz. It provides typical insertion loss of 1.3 dB and rejection up to 50 dB. The device operates within a frequency range extending to 6100 MHz and features a compact 0805 (2012 metric) surface-mount package.

Feature Summary

• LTCC construction for stable high-frequency performance
• Compact 0805 surface-mount footprint
• High stopband rejection capability

Applications

• RF signal filtering
• Wireless communication systems
• Test and measurement equipment

Procurement Notes

Verify the specific datasheet version and manufacturer documentation to confirm electrical parameters and mechanical dimensions. Ensure compatibility with standard SMT assembly processes for the 0805 package. Cross-reference official specifications against design requirements before procurement.

Selection Notes

Select this component for applications requiring a low-pass response up to 3900 MHz in a minimal footprint. Consider the LTCC technology for thermal stability and the 0805 package for space-constrained PCB layouts. Evaluate insertion loss and rejection specs against system noise floor requirements.

Part Context

This part belongs to the Mini-Circuits LFCG series of low-pass filters. These components utilize Low-Temperature Co-fired Ceramic (LTCC) technology, offering reliable performance in RF environments. The series supports various wireless standards and broadband applications.

Replacement Considerations

Check for direct equivalents such as the HFCG-3800+ if a high-pass response is required instead. Verify pinout and footprint compatibility when substituting with other 0805 LTCC filters from different manufacturers.
