XLF-662M+

Overview

The XLF-662M+ is a two-section reflectionless low-pass filter from Mini-Circuits, designed for RF applications. It features a DC to 6000 MHz passband and a stopband frequency range of 9.2 to 26 GHz. The component has a 3 dB cutoff frequency of 6.74 GHz and operates at a nominal impedance of 50 Ohms. Packaged in a surface-mount technology (SMT) format with a 12-VQFN exposed pad, it utilizes a patented topology that absorbs and terminates stop-band signals internally.

Feature Summary

• Employs a patented two-section reflectionless filter topology
• Internally absorbs and terminates stop-band signals
• Designed for surface-mount integration

Applications

• RF signal conditioning
• Microwave circuit design
• Signal filtering in communication systems

Procurement Notes

Verify the specific datasheet version and package marking when sourcing. Confirm RoHS and REACH compliance status as required by your manufacturing standards. Ensure the supplier provides original manufacturer documentation to validate authenticity. Check for any specific handling instructions related to the exposed pad thermal termination.

Selection Notes

Select this component when internal termination of reflected energy is critical to system stability. The reflectionless design prevents signal re-reflection into sensitive source stages. Verify that the 6.74 GHz cutoff meets the specific spectral requirements of the application. Ensure the 12-VQFN package footprint aligns with the PCB layout constraints.

Part Context

Mini-Circuits specializes in RF, IF, and microwave components ranging from DC to 86 GHz. The XLF series represents their line of reflectionless filters, which distinguish themselves by absorbing out-of-band energy rather than reflecting it. This approach enhances performance in multi-stage designs where signal integrity is paramount.
