LFCN-1282+

Overview

The LFCN-1282+ is a low-pass filter manufactured by Mini-Circuits, designed for microwave communication systems. It operates from DC to 12.8 GHz with a cutoff frequency of 13.9 GHz. The component features a 50 Ohm impedance and utilizes LTCC technology within an FV1206-4 surface-mount package. This filter enables designers to effectively reject unwanted harmonics in RF applications.

Feature Summary

• Rejects unwanted harmonics in microwave communication systems
• Utilizes LTCC technology for compact surface-mount integration
• Provides stable performance across the specified frequency range

Applications

• Microwave communication system design
• Harmonic rejection in RF circuits
• Signal filtering in upconverter assemblies

Procurement Notes

Verify the specific ordering suffix and tape-and-reel configuration when sourcing. Confirm that the component meets the required RoHS compliance standards for your assembly process. Ensure compatibility with standard SMT reflow profiles for the FV1206-4 package type during production planning.

Selection Notes

Select this component for applications requiring harmonic suppression up to 13.9 GHz. The 50 Ohm impedance matches standard RF transmission lines. Consider the small FV1206-4 footprint for space-constrained PCB layouts where LTCC reliability is preferred over other filter technologies.

Part Context

Mini-Circuits specializes in RF, IF, and microwave components ranging from DC to 86 GHz. The LFCN series represents their line of ceramic filters built using Low Temperature Co-fired Ceramic (LTCC) technology. These components are engineered for high performance and consistency in demanding electronic environments.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify electrical specifications against potential alternatives to ensure cutoff frequency and impedance matching requirements are met.
