ZXLF-K332+

Overview

The ZXLF-K332+ is a reflectionless low-pass filter from Mini-Circuits, operating from DC to 3250 MHz. It features a cutoff frequency of 4120 MHz with an average input power rating of 2.0 W. The component utilizes the UK3042 case style and maintains a 50 Ohm impedance. Typical insertion loss within the passband ranges from 0.35 dB to 0.42 dB across frequencies up to 15 MHz.

Feature Summary

• Reflectionless architecture minimizes signal reflections for improved system stability
• Broadband operation covering DC to 3250 MHz range
• Designed for signal conditioning applications in RF and microwave circuits

Applications

• RF signal conditioning
• Microwave circuit design
• IF filtering systems

Procurement Notes

Verify the exact part number suffix and manufacturer documentation before procurement. Confirm that the UK3042 package matches your PCB footprint requirements. Ensure the 2.0 W average input power rating aligns with your system's thermal and power constraints. Cross-reference the datasheet specifications against your specific frequency and impedance needs to guarantee compatibility.

Selection Notes

Select this component when reflectionless performance is critical to prevent standing waves in the circuit. The 4120 MHz cutoff provides a margin above the 3250 MHz operational limit. Consider the UK3042 package dimensions during layout planning. Verify that the 50 Ohm impedance matches the rest of the transmission line structure to minimize mismatch losses.
