VLF-3000+

Overview

The VLF-3000+ is a connectorized low-pass filter from the Mini-Circuits VLF series, designed for signal conditioning applications. It operates within a frequency range of 0 Hz to 3 GHz and maintains a system impedance of 50 ohms. The component utilizes SMA connectors for installation and exhibits an insertion loss of 0.72 dB. It is engineered to function reliably across a minimum operating temperature of -55°C and a maximum operating temperature of +100°C.

Feature Summary

• Provides effective low-pass filtering with a cutoff frequency up to 3 GHz
• Features robust SMA connectorized design for reliable in-line integration
• Operates within an extended industrial temperature range

Applications

• RF signal conditioning circuits
• Harmonic suppression in communication systems
• Interference filtering in test and measurement equipment

Procurement Notes

Verify the specific datasheet version when sourcing, as Mini-Circuits may update specifications over time. Confirm that the SMA interface matches your system requirements. Ensure the operating environment stays within the specified -55°C to +100°C range to maintain performance integrity. Cross-reference the part number VLF-3000+ with official manufacturer documentation to avoid counterfeit components.

Selection Notes

Select this component when a low-pass filter with a 3 GHz cutoff is required. The 50-ohm impedance ensures compatibility with standard RF transmission lines. Consider the 0.72 dB insertion loss for signal budget calculations. The wide temperature range makes it suitable for harsh environments where other filters might fail.

Part Context

This component belongs to the VLF series of connectorized low-pass filters by Mini-Circuits. The series offers various cutoff frequencies, with the VLF-3000+ specifically targeting applications requiring attenuation above 3 GHz. It shares the same physical form factor and impedance characteristics as other models in the lineup, differing primarily in its electrical cutoff specification.

Replacement Considerations

Direct substitutes include other VLF series models with similar cutoff frequencies, such as the VLF-4000+. Verify that any replacement maintains the 50-ohm impedance and SMA connector type to ensure mechanical and electrical compatibility without circuit modification.
