VLFG-3500+

Overview

The VLFG-3500+ is a low-pass RF filter manufactured by Mini-Circuits, designed for signal processing applications from DC to 3500 MHz. It features an SMA connector interface and operates within a 50 Ohm system impedance. The component provides a 3dB cutoff frequency of 3970 MHz, ensuring effective attenuation of higher frequencies while maintaining signal integrity in the passband. Key electrical specifications include a typical insertion loss of 0.5 dB and a stopband rejection of 47 dB. The device supports up to 4.5W of RF input power and offers a wide operating temperature range, making it suitable for demanding environments.

Feature Summary

• Provides effective high-frequency attenuation with a defined 3dB cutoff point
• Supports high RF input power handling capabilities
• Maintains low insertion loss for efficient signal transmission
• Constructed using LTCC technology for reliability

Applications

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

Procurement Notes

Verify the exact part number suffix and connector type upon ordering. Confirm that the required power handling and frequency specifications align with your system design. Ensure compatibility with existing SMA interfaces. Check for any specific environmental ratings if operating outside standard conditions. Validate datasheet revisions for the most current performance metrics before finalizing procurement decisions.

Selection Notes

Select this component when a sharp cutoff below 4 GHz is required with minimal signal degradation. Consider its power handling limits relative to your maximum expected RF input. Evaluate the physical size constraints against available PCB space. Compare insertion loss requirements with other available filters in the same frequency range. Ensure the operating temperature range meets your application's environmental demands.

Part Context

This component belongs to Mini-Circuits' VLFG series of low-pass filters, which utilize LTCC technology for compact form factors and reliable performance. The series is designed for general-purpose RF applications requiring effective harmonic rejection and noise filtering. These filters are commonly integrated into modular RF systems where consistent impedance matching and stable electrical characteristics are critical for overall system performance.
