ZXLF-K641M+

Overview

The ZXLF-K641M+ is a reflectionless low-pass filter from Mini-Circuits, designed for signal conditioning applications. It operates with a frequency range from DC to 500 MHz. The device features a 3.3 dB bandwidth and a cutoff frequency of 700 MHz. It provides stopband performance from 1.1 GHz to 11 GHz. The component utilizes the UK3042 case style and employs a novel two-section topology that absorbs and terminates stopband energy.

Feature Summary

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

Applications

• Signal conditioning in RF systems
• Harmonic suppression in communication equipment

Procurement Notes

Verify the specific datasheet version and electrical characteristics directly from Mini-Circuits official documentation before integration. Confirm that the UK3042 package dimensions and pinout match your PCB layout requirements. Ensure thermal management strategies align with the component's power handling capabilities as defined in the manufacturer's specifications.

Selection Notes

Select this component when reflectionless operation is critical to maintain system stability in the stopband. The dual specification of a 500 MHz passband and 700 MHz cutoff offers flexibility for filtering requirements. Consider the UK3042 form factor for compact integration into dense RF assemblies requiring precise signal integrity.

Part Context

This part belongs to the XLF series of reflectionless filters by Mini-Circuits. These components are engineered to address common issues with traditional filters where out-of-band signals reflect back into the source. The series is widely used in modern RF designs where signal purity and source protection are paramount.
