VLFG-400+

Overview

The VLFG-400+ is a rugged, unibody low-pass filter manufactured by Mini-Circuits. It operates within a DC to 400 MHz bandwidth and features a 50-ohm impedance system. The component utilizes SMA connectors for inline integration. Designed for high reliability, it provides good matching within the passband and is suitable for demanding RF applications requiring stable signal filtering.

Feature Summary

• Rugged unibody construction for durability
• SMA connector interface for easy integration
• Good impedance matching within the passband

Applications

• RF test and measurement equipment
• Wireless communication systems
• Signal conditioning in instrumentation

Procurement Notes

Verify the specific datasheet version for precise insertion loss and rejection specifications. Confirm SMA connector gender and cable assembly requirements if applicable. Ensure environmental ratings match operational conditions. Cross-reference part numbers with official Mini-Circuits documentation to avoid counterfeit components.

Selection Notes

Select this model for applications requiring a fixed low-pass characteristic up to 400 MHz. Consider the unibody form factor for mechanical stability. Evaluate insertion loss and stopband attenuation against system noise floor requirements. Ensure compatibility with existing SMA infrastructure.

Part Context

Part of the Mini-Circuits VLFG series of low-pass filters. This series offers various cutoff frequencies while maintaining consistent rugged unibody construction and 50-ohm impedance characteristics across the product line.

Replacement Considerations

Check Mini-Circuits documentation for direct substitutes with different cutoff frequencies or connector types. Verify electrical performance equivalence before substitution.
