VLF-400+

Overview

The VLF-400+ is a low-pass filter manufactured by Mini-Circuits, designed for radio frequency applications. It features a cutoff frequency of 560 MHz and operates within a DC to 400 MHz bandwidth range. The component provides an insertion loss of 2.77 dB and utilizes SMA connectors for in-line module integration. Constructed using LTCC technology, it maintains a 50Ω impedance characteristic suitable for standard RF systems.

Feature Summary

• SMA connector interface
• Low insertion loss design

Applications

• RF signal filtering
• Harmonic suppression
• Base station equipment

Procurement Notes

Verify the specific datasheet version for the VLF-400+ model to confirm exact electrical parameters and mechanical dimensions. Ensure compatibility with existing SMA interfaces and 50Ω system requirements before integration. Cross-reference official Mini-Circuits documentation for any updates regarding pinout or thermal specifications.

Selection Notes

Select this component when a low-pass filter with a 560 MHz cutoff is required. Consider the 2.77 dB insertion loss impact on signal integrity. Verify that the LTCC package style meets space constraints. Confirm SMA connector orientation matches the circuit board layout.

Part Context

This part belongs to the Mini-Circuits VLF series of low-pass filters. These components are engineered for general-purpose RF filtering tasks. The series offers various cutoff frequencies to suit different application needs while maintaining consistent impedance and connector types across the product line.

Replacement Considerations

Consult Mini-Circuits official substitution guides for compatible alternatives. Verify that any substitute maintains the 50Ω impedance and SMA connector type. Ensure the replacement filter meets or exceeds the 560 MHz cutoff requirement and similar insertion loss characteristics.
