ZXLF-K73+

Overview

The ZXLF-K73+ is a reflectionless low pass filter from Mini-Circuits designed for signal conditioning applications. It operates over a frequency range of DC to 7000 MHz with a 50 Ohm impedance. The component utilizes a novel topology that absorbs stop band signals internally, eliminating the need for external termination resistors. It features a 2.92 mm connector and is housed in the UK3042 case style. The maximum operating temperature is +105 C.

Feature Summary

• Employs reflectionless topology to absorb stop band signals internally
• Operates within a DC to 7000 MHz frequency range
• Features 50 Ohm impedance matching
• Utilizes 2.92 mm connector termination style

Applications

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

Procurement Notes

Verify the specific datasheet version and ordering suffixes when sourcing. Confirm the 2.92 mm connector type and UK3042 package dimensions match your PCB layout requirements. Ensure the DC to 7000 MHz specification aligns with your system's bandwidth needs before procurement.

Selection Notes

Select this component when internal absorption of out-of-band energy is required to prevent reflections. The 50 Ohm impedance suits standard RF systems. Consider the 2.92 mm interface for high-frequency integrity. Verify thermal limits against your operational environment.

Part Context

This part belongs to the ZXLF series by Mini-Circuits, which specializes in reflectionless filters. These components are engineered for RF, IF, and microwave frequencies up to 86 GHz. The series distinguishes itself by integrating termination directly into the filter structure.
