LFCN-3000D+

Overview

The LFCN-3000D+ is a surface-mount LTCC low-pass filter designed for RF applications. It provides a passband from DC to 3000 MHz with a 50Ω impedance. The device features an insertion loss of 1.2 dB and operates within a temperature range of -40°C to +85°C. It utilizes the FV1206 case style, ensuring compact integration into high-frequency circuits while maintaining signal integrity across the specified frequency band.

Feature Summary

• Utilizes Low Temperature Co-fired Ceramic (LTCC) technology for robust construction
• Provides effective attenuation above the 3000 MHz cutoff frequency
• Designed for surface-mount assembly in space-constrained environments

Applications

• RF front-end filtering in communication systems
• Signal conditioning in microwave circuits
• Harmonic suppression in transmitter outputs

Procurement Notes

Verify the specific datasheet revision and test board conditions (TB-270) when evaluating performance metrics. Confirm that the FV1206 package dimensions align with your PCB footprint requirements. Ensure thermal management strategies account for the derating specifications at elevated temperatures to maintain operational reliability.

Selection Notes

Select this component when a sharp cutoff near 3 GHz is required in a minimal footprint. The LTCC construction offers stability compared to other ceramic technologies. Consider the 1.2 dB insertion loss impact on system noise figure. Verify compatibility with standard SMT reflow processes for the FV1206 package type.

Part Context

Mini-Circuits manufactures this component as part of its extensive portfolio of RF and microwave filters. The LFCN series specifically targets applications requiring reliable low-pass filtering in compact form factors. This model represents a standard solution for frequencies up to 3 GHz in modern electronic designs.

Replacement Considerations

Consult Mini-Circuits official substitution guides for verified equivalents. Generic cross-references may not match the precise LTCC characteristics or FV1206 footprint. Validate any alternative against the original electrical specifications before implementation.
