VLFG-575+

Overview

The VLFG-575+ is a low-pass filter from Mini-Circuits designed for RF applications. It operates with a cutoff frequency of 575 MHz and maintains a 50 Ohm impedance. The device supports an input power handling capacity of up to 3.5W. It features a wide operating temperature range spanning from -55°C to +125°C. The unit utilizes SMA connectors for interface connections and is constructed in a rugged unibody style.

Feature Summary

• Provides high rejection in the stopband while maintaining good matching within the passband
• Constructed in a rugged unibody design for durability
• Supports high RF input power handling capabilities

Applications

• RF signal filtering in communication systems
• Harmonic suppression in transmitter chains
• Signal conditioning in test and measurement equipment

Procurement Notes

Verify the specific connector type and package style required for your assembly, as variations may exist across different production runs or distributor listings. Confirm that the 3.5W power rating aligns with your system's maximum expected input levels to ensure reliable operation within the specified temperature range. Cross-reference the manufacturer part number with official datasheets to confirm technical specifications before finalizing procurement orders.

Selection Notes

Select this component when a sharp cutoff near 575 MHz is required with robust power handling. The unibody construction makes it suitable for environments requiring mechanical stability. Ensure the SMA interface matches your board layout constraints. Consider the wide temperature range if the application involves extreme thermal conditions. Verify impedance matching requirements against the 50 Ohm specification provided by the manufacturer.

Part Context

This component belongs to the VLFG series of low-pass filters manufactured by Mini-Circuits. The series is characterized by its use in RF and microwave circuits where effective harmonic rejection and passband integrity are critical. These filters are commonly integrated into systems requiring precise frequency control and signal purity across various industrial and commercial applications.

Replacement Considerations

Consult official Mini-Circuits documentation for direct substitutes. Alternative models within the same series may offer similar cutoff frequencies but different power ratings or connector styles. Verify compatibility with existing circuit designs before substitution.
