LFCN-320D+

Overview

The LFCN-320D+ is an LTCC low-pass filter with a cutoff frequency of 320 MHz and 50Ω impedance. It operates from DC to 320 MHz, providing effective signal filtering in RF applications. The component utilizes ceramic technology for stability and is housed in a compact FV1206 surface-mount package. Designed for high performance, it offers good stopband rejection and low insertion loss within the passband, making it suitable for various communication systems requiring precise frequency control.

Feature Summary

• Utilizes LTCC ceramic technology for robust construction
• Provides effective low-pass filtering up to 320 MHz
• Features a compact surface-mount package design
• Maintains 50Ω impedance matching

Applications

• RF front-end filtering
• Communication system signal conditioning
• Base station equipment

Procurement Notes

Verify the exact datasheet specifications directly from Mini-Circuits before integration. Confirm that the FV1206 package dimensions align with your PCB land pattern requirements. Ensure the 320 MHz cutoff frequency meets your specific application needs. Check for any RoHS compliance documentation if required by your manufacturing standards. Validate thermal handling capabilities for your intended operating environment.

Selection Notes

Select this component when a sharp cutoff near 320 MHz is required in a small form factor. Consider the LTCC construction for better environmental stability compared to other filter types. Evaluate the insertion loss characteristics against your system's noise budget. Compare the physical size constraints with alternative packages if space is limited. Ensure the 50Ω impedance matches your transmission line requirements.

Part Context

The LFCN series from Mini-Circuits represents a line of low-cost, high-performance ceramic filters. These components are designed for general-purpose RF applications where size and cost are critical factors. The LFCN-320D+ specifically targets frequencies up to 320 MHz, offering a balance between performance and affordability for mass-produced electronic devices.

Replacement Considerations

Check Mini-Circuits' official substitution guide for compatible alternatives. Verify that any substitute maintains the same 320 MHz cutoff and 50Ω impedance. Ensure the replacement part fits the FV1206 footprint or requires adapter changes. Confirm electrical performance metrics match or exceed original specifications.
