XLF-42M+

Overview

The XLF-42M+ is a two-section reflectionless low-pass filter from Mini-Circuits' X-Series, designed for RF applications. It operates with a cutoff frequency of 350 MHz and supports a bandwidth of 0.35 GHz. The device features a passband extending from DC to 300 MHz and maintains a characteristic impedance of 50 Ohms. It utilizes a novel topology that absorbs and terminates stopband energy, providing ultra-high rejection in the stopband. The component is housed in a compact 32-VFQFN package with an exposed pad, suitable for surface-mount technology.

Feature Summary

• Employs a novel reflectionless topology that absorbs and terminates stopband energy to prevent signal reflections.

Applications

• RF front-end filtering
• Signal integrity enhancement in communication systems

Procurement Notes

Verify the specific datasheet version and ordering suffixes when sourcing. Confirm the package type matches the design requirements. Ensure compatibility with the intended operating frequency range. Check for any recent updates to the technical specifications. Validate the manufacturer's authenticity through authorized channels.

Selection Notes

Select this component for applications requiring high stopband rejection without signal reflections. Consider the 350 MHz cutoff frequency for appropriate signal filtering needs. Evaluate the 32-VFQFN package size for space-constrained designs. Assess the 50 Ohm impedance match for system integration. Review the thermal performance of the exposed pad for heat dissipation.
