VLF-105+

Overview

The VLF-105+ is a coaxial low-pass RF filter manufactured by Mini-Circuits, designed for signal conditioning in radio frequency applications. It operates with a DC to 105 MHz passband and features a 50 Ohm impedance. The component utilizes SMA connectors for in-line module integration. Key electrical specifications include a cutoff frequency of 180 MHz and a bandwidth of 3.1 dB. It provides 20 dB rejection at 250 MHz and maintains a Voltage Standing Wave Ratio (VSWR) of 1.2:1. The unit supports an input power level of 0 dBm across an operating temperature range from -55°C to +100°C.

Feature Summary

• Coaxial unibody construction for rugged performance
• SMA connector interface for in-line module integration
• Low insertion loss within the specified passband

Applications

• Radio frequency signal filtering
• Communication system interference suppression
• Test and measurement equipment signal conditioning

Procurement Notes

Verify the specific datasheet version for the VLF-105+ to confirm exact connector orientation and mechanical dimensions prior to procurement. Ensure that the required input power handling and thermal operating conditions align with the system design constraints. Cross-reference the part number suffixes if alternative packaging or connector types are required for the specific assembly process.

Selection Notes

Select the VLF-105+ when a compact coaxial low-pass filter with SMA connectivity is required for frequencies up to 105 MHz. Consider this component for applications demanding high matching accuracy and robust physical construction. Evaluate the 20 dB rejection specification against the specific harmonic or noise frequencies present in the target circuit to ensure adequate attenuation performance.
