XLF-173+

Overview

The XLF-173+ is a reflectionless low-pass filter manufactured by Mini-Circuits, designed for radio frequency applications. It features a cutoff frequency of 17000 MHz and operates with a nominal impedance of 50 Ohms. The component utilizes a novel topology that absorbs and terminates stop-band signals, preventing signal reflections. It is available in a surface-mount technology (SMT) package, specifically a 12-VQFN exposed pad configuration. The device complies with RoHS and REACH standards.

Feature Summary

• Employs a reflectionless topology to absorb and terminate stop-band signals
• Provides low-pass filtering functionality up to 17 GHz
• Designed for surface-mount integration

Applications

• RF signal conditioning
• Microwave circuit design
• Signal integrity management in high-frequency systems

Procurement Notes

Verify the specific datasheet version and environmental rating (ENV80) before procurement. Confirm the package type matches the 12-VQFN exposed pad specification. Ensure compliance requirements align with project needs. Check for any ordering suffix variations that may affect performance or termination. Validate supplier authenticity through authorized channels.

Selection Notes

Select this component when reflectionless behavior is critical to system stability. The 17 GHz cutoff suits applications requiring wideband low-pass characteristics. Consider the SMT package for automated assembly processes. Evaluate the 50 Ohm impedance match against system requirements. Assess the thermal and mechanical properties of the VQFN package for the intended environment.
