VLF-52+

Overview

The VLF-52+ is a low-pass RF filter manufactured by Mini-Circuits, designed for signal conditioning applications. It features an LTCC internal structure and operates within a passband frequency range of DC to 52 MHz. The component utilizes SMA connectors and provides a typical insertion loss of 1.2 dB. It achieves high rejection levels, specifically 20 dB at 140 MHz and 50 dB at 180 MHz. The unit maintains a VSWR of 1.4:1 and is housed in a compact coaxial module measuring 1.43 inches in length.

Feature Summary

• Utilizes internal LTCC technology for consistent performance
• Provides high rejection capabilities for harmonic suppression
• Features compact coaxial design with integrated SMA connectors

Applications

• Test setups requiring precise signal filtering
• S-band upconverter assemblies
• RF signal conditioning circuits

Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturer documentation may be updated. Confirm that the SMA connector orientation matches your system requirements. Ensure environmental conditions align with the component's operational specifications. Cross-reference part numbers carefully to distinguish between standard and specialized variants. Validate compatibility with your PCB layout or cable assembly constraints before finalizing procurement decisions.

Selection Notes

Select this component when a sharp cutoff below 52 MHz is required alongside low insertion loss. The LTCC construction ensures repeatability compared to discrete implementations. Consider the physical dimensions if space is constrained in the signal chain. Evaluate the rejection profile against potential interference frequencies in the 140 MHz to 180 MHz range. This filter suits applications demanding stable performance without complex external tuning.
