DLFCG-540+

Overview

The DLFCG-540+ is an LTCC differential low pass filter designed for balanced 100Ω lines, offering a passband from DC to 540 MHz. It features a compact 0805 (2012 metric) surface-mount package with six pads. The component provides typical insertion loss ranging from 0.13 dB at 25 MHz to 0.27 dB at 150 MHz. Stopband attenuation reaches approximately 38.36 dB at 25 MHz and decreases to 22.93 dB at 150 MHz. This device supports wideband signal processing applications requiring high signal integrity.

Feature Summary

• LTCC technology ensures stable performance with low temperature drift
• Differential design optimized for balanced 100Ω transmission lines
• Compact 0805 SMD footprint facilitates dense PCB layouts

Applications

• Wideband signal processing circuits
• Balanced RF line filtering
• Wireless communication systems

Procurement Notes

Verify the specific datasheet version when ordering, as Mini-Circuits may update performance curves or mechanical drawings over time. Confirm that the 0805 package dimensions match your PCB land pattern requirements. Ensure the supplier provides RoHS compliance documentation if required by your manufacturing standards. Check for any specific handling instructions related to LTCC materials during assembly.

Selection Notes

Select this component when differential filtering is required for signals below 540 MHz. The 100Ω impedance matching makes it suitable for balanced interfaces rather than standard 50Ω single-ended lines. Consider the 0805 size constraint against available board space. Evaluate the insertion loss characteristics against system noise budget requirements for frequencies up to 150 MHz.

Part Context

This part belongs to Mini-Circuits' LTCC filter series, which utilizes Low Temperature Co-fired Ceramic technology. These components are engineered for reliability in commercial and industrial environments. The DLFCG-540+ specifically addresses the need for differential filtering in modern RF designs where common-mode noise rejection and balanced signal integrity are critical.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Consult Mini-Circuits technical support for potential alternatives if this specific model is discontinued or unavailable.
