LFCN-320+

Overview

The LFCN-320+ is a low-pass filter designed for RF applications, featuring a cutoff frequency of 320 MHz and a characteristic impedance of 50 ohms. It utilizes LTCC technology to provide compact integration within signal chains. The component operates from DC up to the specified cutoff point, ensuring effective attenuation of higher frequencies while maintaining signal integrity in the passband.

Feature Summary

• Utilizes LTCC construction for robust performance
• Provides low-pass filtering functionality
• Designed for 50-ohm system integration

Applications

• RF signal conditioning
• Harmonic suppression
• Interference mitigation

Procurement Notes

Verify the specific suffix requirements before ordering. The standard LFCN-320+ model does not support DC continuity between input and output ports. If DC pass-through capability is required for the application, confirm availability of the LFCN-320D+ variant, which offers high isolation to ground while maintaining DC connectivity.

Selection Notes

Select this component when a fixed 320 MHz cutoff is necessary for noise reduction or harmonic control. Ensure the design accommodates the FV1206 package dimensions. Consider the LFCN-320D+ if the circuit topology requires direct DC coupling across the filter element without compromising isolation characteristics.

Part Context

This part belongs to Mini-Circuits' ceramic filter series, leveraging Thin Film and LTCC technologies for miniaturization. It serves as a passive component for managing spectral content in communication systems. The product line emphasizes reliability and consistent electrical performance across varying environmental conditions.

Replacement Considerations

The LFCN-320D+ is an official alternative that provides DC pass-through capability. Verify pinout compatibility and thermal management requirements when substituting components to ensure the new part meets the original design's physical and electrical constraints.
