ZXLF-K192+

Overview

The ZXLF-K192+ is a reflectionless low-pass filter module from Mini-Circuits, designed for RF applications up to 2.4 GHz. It features a cutoff frequency of 1900 MHz with a passband extending from DC. The device provides high attenuation in the stopband, specified at 15-22 dB, and maintains an insertion loss of 2.5 dB within the passband. Housed in a compact module package measuring 17.78 mm x 12.70 mm x 11.27 mm, it supports base mounting. The component operates reliably under standard conditions and complies with RoHS3 standards.

Feature Summary

• Reflectionless architecture eliminates harmonic radiation typically associated with traditional low-pass filters
• High stopband attenuation ensures effective suppression of unwanted signals above the cutoff frequency
• Compact module form factor facilitates integration into space-constrained RF systems

Applications

• Telecommunications infrastructure
• Military and defense systems
• 4G wireless networks
• GPS receivers
• VHF/UHF radio equipment

Procurement Notes

Verify the specific datasheet revision and ECO number against the manufacturer's official documentation before finalizing design specifications. Confirm that the module package dimensions and mounting requirements align with the target PCB layout. Ensure environmental compliance with RoHS3 standards is required for the intended market. Cross-reference the part number suffix to confirm availability of the exact variant needed for the application.

Selection Notes

Select this component when harmonic suppression is critical without adding parasitic resonances. The reflectionless design prevents signal reflections that can destabilize upstream amplifiers. Consider the 2.5 dB insertion loss impact on system noise figure. Evaluate the module size against available board space. Verify compatibility with the operating frequency range up to 2.4 GHz for optimal performance.

Part Context

This component belongs to the ZXLF series of reflectionless filters by Mini-Circuits. The series addresses common issues in RF signal chains where traditional filters cause impedance mismatches. Designed for robust performance in demanding environments, these modules support frequencies from DC to high microwave ranges. The ZXLF-K192+ specifically targets applications requiring clean signal filtering in the VHF/UHF bands.

Replacement Considerations

Direct substitutes include other ZXLF series models with similar cutoff frequencies. Check Mini-Circuits documentation for equivalent parts with adjusted bandwidth or power handling. Ensure any replacement maintains the reflectionless characteristic to preserve system stability.
