LFCG-3400+

Overview

The LFCG-3400+ is an LTCC low pass filter manufactured by Mini-Circuits. It provides a passband from DC to 3400 MHz with a cutoff frequency of 3.8 GHz. The component operates at a nominal impedance of 50Ω and features a compact 0805 (2012 Metric) surface-mount package with eight pads. Key electrical specifications include insertion loss of 1.3 dB and rejection up to 50 dB.

Feature Summary

• Utilizes LTCC technology for robust construction
• Compact 0805 surface-mount footprint
• High rejection capability up to 50 dB

Applications

• RF signal filtering in communication systems
• Harmonic suppression in RF circuits
• Signal conditioning in wireless devices

Procurement Notes

Verify the exact datasheet revision and manufacturer source before procurement. Confirm that the ordering suffix matches the required specifications, as suffixes may indicate variations in function or performance. Ensure compatibility with standard 0805 footprints during design integration.

Selection Notes

Select this component for applications requiring a low-pass response up to 3400 MHz in a minimal space-constrained environment. Consider the 1.3 dB insertion loss and 50 ohm impedance match when designing matching networks. Evaluate thermal and mechanical stability requirements against LTCC capabilities.

Part Context

This part belongs to the LFCG series of low pass filters from Mini-Circuits. The series offers various cutoff frequencies ranging from DC to 6100 MHz within the same 0805 package family, allowing for standardized design processes across different frequency bands while maintaining consistent physical dimensions.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult Mini-Circuits sales for potential alternatives or cross-reference with other manufacturers offering similar LTCC low-pass filters in the 0805 package with comparable cutoff frequencies.
