LFCN-1000D+

Overview

The LFCN-1000D+ is a low-pass ceramic filter from Mini-Circuits, utilizing LTCC technology for compact SMD packaging. It operates with a cutoff frequency of 1000 MHz and maintains a standard 50Ω impedance. The component handles up to 1W RF input power and exhibits typical passband insertion loss ranging from 1.2dB to 1.9dB. Designed for robust performance, it functions reliably within an extended temperature range of -55°C to +125°C.

Feature Summary

• Utilizes mature LTCC technology for stable performance and low temperature drift
• Provides effective suppression of high-frequency harmonics and RF clutter
• Features compact surface-mount design suitable for space-constrained PCB layouts

Applications

• Multi-band RF filtering in wireless communication devices
• Signal conditioning in industrial measurement and control systems
• Harmonic suppression in broadcast RF systems

Procurement Notes

Verify the specific suffix 'D+' against official Mini-Circuits documentation to confirm package type and termination style. Ensure compatibility with standard LTCC footprint dimensions during PCB layout. Cross-reference datasheet electrical specifications for your operating frequency band to validate insertion loss requirements.

Selection Notes

Select this component when a sharp cutoff near 1000 MHz is required with minimal signal degradation in the passband. Consider the 1W power handling capability for moderate power applications. Evaluate the -55°C to +125°C temperature range against environmental conditions to ensure long-term reliability without performance drift.

Part Context

This part belongs to the LFCN series of LTCC low-pass filters from Mini-Circuits. These components are designed to replace bulkier traditional filter technologies while offering superior size reduction. The series supports various cutoff frequencies, providing designers with standardized solutions for RF front-end filtering across multiple commercial and industrial bands.

Replacement Considerations

Consult Mini-Circuits official substitution guides for equivalent parts with adjusted cutoff frequencies or different package footprints. Verify that any alternative maintains the same 50Ω impedance and LTCC construction to preserve circuit matching.
