VLFG-900+

Overview

The VLFG-900+ is a low-pass filter manufactured by Mini-Circuits, designed for radio frequency applications. It features an SMA connector and operates within a 50-ohm system impedance. The component utilizes LTCC technology to provide a passband from DC to 850 MHz. It offers low insertion loss and excellent power handling capability, supporting up to 4.5W of RF input power. The device ensures wide operating temperature stability and high rejection in the stopband.

Feature Summary

• Utilizes LTCC technology for compact form factor and reliable performance
• Provides low insertion loss across the designated passband
• Supports high RF input power handling up to 4.5W
• Features SMA connectors for easy integration into RF systems

Applications

• RF signal filtering in communication systems
• Harmonic suppression in transmitter chains
• Interference rejection in receiver front-ends
• General-purpose low-pass filtering in test and measurement equipment

Procurement Notes

Verify the specific datasheet version for the VLFG-900+ to confirm mechanical dimensions and electrical specifications prior to procurement. Ensure compatibility with SMA connectors and 50-ohm system requirements. Check for any updates regarding material composition or manufacturing standards that may affect compliance with current industry regulations.

Selection Notes

Select the VLFG-900+ when a low-pass filter with a cutoff near 900 MHz is required. Consider its 4.5W power handling if high-power signals are present. Verify that the SMA interface matches existing board layouts. Compare stopband rejection characteristics against other models in the VLFG series to ensure adequate interference suppression for the specific application environment.

Part Context

Mini-Circuits produces a range of RF filters under the VLFG series, utilizing LTCC technology for robust performance. The VLFG-900+ specifically targets applications requiring filtering below 900 MHz. This component fits within the broader portfolio of passive RF components designed for consistent reliability and performance across various frequency bands.

Replacement Considerations

Consult Mini-Circuits documentation for direct substitutes within the VLFG series. Alternative part numbers may offer different cutoff frequencies or power ratings. Ensure any replacement maintains SMA connectivity and 50-ohm impedance to preserve system integrity without redesigning surrounding circuitry.
