VLF-3400+

Overview

The VLF-3400+ is a low-pass filter manufactured by Mini-Circuits, designed for radio frequency applications. It features a cutoff frequency of 3.95 GHz and operates within a DC to 3400 MHz passband. The component utilizes LTCC technology and maintains a 50Ω impedance. It is housed in the FF704 case style with SMA connectors. The device handles up to 4.5W of RF input power, with linear derating to 3W at 100°C ambient temperature.

Feature Summary

• Utilizes LTCC technology for compact integration
• Provides excellent power handling capability
• Features low insertion loss characteristics

Applications

• Automotive devices
• RF signal filtering
• Microwave circuit design

Procurement Notes

Verify the specific datasheet version when sourcing the VLF-3400+. Confirm that the SMA connector type matches your system requirements. Ensure thermal management accounts for the specified power derating at elevated temperatures. Check for any updated case style specifications or alternative suffixes that may affect compatibility.

Selection Notes

Select this component for applications requiring a sharp cutoff near 3.4 GHz. The 50Ω impedance ensures compatibility with standard RF systems. Consider the FF704 package dimensions for PCB layout constraints. Evaluate the power handling limits against peak signal levels to prevent performance degradation.
