XLF-172H+

Overview

The XLF-172H+ is a reflectionless low pass filter manufactured by Mini-Circuits, operating from DC to 2000 MHz with a 50Ω impedance. It utilizes a three-section novel topology that absorbs and terminates stopband signals internally rather than reflecting them. The component features an insertion loss of 3dB and is housed in a 24-VFQFN exposed pad package with dimensions of 0.157" L x 0.157" W (4.00mm).

Feature Summary

• Employs a three-section reflectionless topology that absorbs and terminates stopband signals internally.
• Operates as a low pass filter covering the frequency range from DC to 2000 MHz.
• Designed for 50Ω systems to prevent signal reflections.

Applications

• RF and IF system filtering
• Microwave component integration
• Signal chain configuration

Procurement Notes

Verify the specific datasheet version and ordering suffixes directly with Mini-Circuits or authorized distributors. Confirm package type and electrical specifications match design requirements before procurement. Ensure compatibility with surface mount assembly processes given the VFQFN form factor.

Selection Notes

Select this component when internal termination of stopband energy is required to maintain system stability. The reflectionless design prevents reflected signals from interfering with upstream components. Verify that the 2000 MHz cutoff and 3dB insertion loss meet the specific application bandwidth and loss budget constraints.

Part Context

This part belongs to Mini-Circuits' XLF series of reflectionless filters. These components are designed for high-performance RF and microwave applications where traditional reflective filters might cause instability due to standing waves. The H+ suffix typically indicates lead-free compliance within the manufacturer's product line.
