VLFG-1000+

Overview

The VLFG-1000+ is a low-pass filter manufactured by Mini-Circuits, designed for RF and microwave applications. It features a passband extending from DC to 1000 MHz with a 50 Ohm impedance. The component utilizes LTCC technology housed in the FF704 case style and complies with ENV113 environmental ratings. Termination is provided via SMA connectors, ensuring reliable signal integrity across the specified frequency range.

Feature Summary

• LTCC construction for robust performance
• SMA connector termination
• DC to 1000 MHz passband

Applications

• RF signal conditioning
• Harmonic suppression
• Base station infrastructure

Procurement Notes

Verify the specific datasheet revision and environmental compliance documentation prior to procurement. Confirm that the SMA termination type matches the system interface requirements. Ensure the LTCC package dimensions align with the PCB layout constraints. Cross-reference the part number suffix to confirm RoHS status and manufacturing origin details.

Selection Notes

Select this component when a sharp cutoff below 1000 MHz is required. Consider the FF704 footprint for board space limitations. Evaluate insertion loss and return loss specifications against system sensitivity needs. Verify compatibility with operating temperature ranges defined by the ENV113 rating.

Part Context

This model belongs to the VLFG series of low-pass filters from Mini-Circuits. The series offers various cutoff frequencies while maintaining consistent 50 Ohm impedance and SMA connectivity.
