ZXLF-K13H+

Overview

The ZXLF-K13H+ is a reflectionless low-pass filter module from Mini-Circuits, designed for RF signal conditioning. It operates with a cutoff frequency of 1.3 GHz and supports a frequency range up to 1000 MHz in its passband definition context, though the model designation implies 1.3 GHz cutoff. The component features a 50 Ohm impedance and utilizes a 2.92mm termination interface. It is housed in a UK3042 case style package. This device is engineered to minimize return loss variations across the stopband, providing stable performance for high-frequency applications.

Feature Summary

• Reflectionless design architecture that maintains consistent return loss throughout the stopband
• Low-pass filtering capability with a specified 1.3 GHz cutoff frequency
• Integrated module construction utilizing a 2.92mm connector interface

Applications

• RF signal conditioning in communication systems
• Harmonic suppression in transmitter chains
• Interference filtering in test and measurement equipment

Procurement Notes

Verify the specific datasheet version for the ZXLF-K13H+ to confirm exact electrical parameters, as cutoff frequencies can vary by revision. Ensure compatibility with 2.92mm mating connectors during integration. Confirm RoHS and REACH compliance status if required for your specific regulatory environment. Cross-reference the UK3042 package dimensions with your mechanical layout constraints before finalizing the design.

Selection Notes

Select this component when stable stopband return loss is critical, as standard filters may exhibit varying reflections. The 50 Ohm impedance matches standard RF infrastructure. Consider the 2.92mm termination for high-frequency integrity up to the module's limits. Evaluate the physical size of the UK3042 package against available board space. Compare insertion loss specifications against system budget requirements.
