XLF-132H+

Overview

The XLF-132H+ is a three-section reflectionless low-pass filter from Mini-Circuits, designed for RF signal conditioning. It features a cutoff frequency of 1.68 GHz and operates within a DC to 1300 MHz passband. The component exhibits an insertion loss of 2.9 dB and maintains a 50 Ohm impedance system. It is housed in a compact 24-VFQFN exposed pad surface-mount package with dimensions of 0.157 inches by 0.157 inches (4.00 mm x 4.00 mm). This topology absorbs stop-band energy to prevent reflections.

Feature Summary

• Employs a novel three-section reflectionless filter topology that absorbs and terminates stop-band energy rather than reflecting it.

Applications

• RF signal conditioning in communication systems
• Test and measurement equipment requiring precise low-pass filtering
• Wireless infrastructure components

Procurement Notes

Verify the specific suffix (+) indicates lead-free compliance when ordering. Confirm the 24-VFQFN package footprint matches your PCB design constraints. Ensure the 1.68 GHz cutoff specification aligns with your system's frequency requirements. Check thermal management needs given the SMT mounting type.

Selection Notes

Select this component when reflectionless performance is critical to maintain system stability across varying load conditions. The 2.9 dB insertion loss represents a trade-off between attenuation and power handling. Consider the small 4.00 mm square footprint for space-constrained designs requiring high-frequency filtering capabilities.

Part Context

This part belongs to Mini-Circuits' XLF series of reflectionless filters. These components utilize proprietary technology to eliminate signal reflections common in traditional LC filters. The series offers various cutoff frequencies while maintaining consistent electrical characteristics and package styles for standardized integration.

Replacement Considerations

The XLF-132H-D+ is the die version of this component. Verify if bare die or packaged form is required for your assembly process. No other direct substitutes are confirmed in public documentation.
